Although there is mention of God saving the Gentiles in the Old Testament, Paul refers to this fact as "The Great Mystery" implying that God did not let people comprehend this fact until he saw the time fit.  Paul implies that this fact was not fully revealed until after the death of Jesus.

God hid this Mystery from some who may have tried to prevent Jesus' death if they knew that His death would allow all people to attain eternal life.  God did not allow their minds to understand His plan, so that they wouldn't interfere with it.
 

Eph 3:6  states that by believing in Jesus Christ, Gentiles can also attain eternal life.  It was revealed that not only will the Jews, God's chosen people, be allowed to fellowship in the Holy Spirit in Heaven, but that the Gentiles will share jointly in God's blessings. 

Isa 66:18-24

18 "And I, because of their actions and their imaginations, am about to come and gather all nations and tongues, and they will come and see my glory. 
19 "I will set a sign among them, and I will send some of those who survive to the nations--to Tarshish, to the Libyans and Lydians (famous as archers), to Tubal and Greece, and to the distant islands that have not heard of my fame or seen my glory. They will proclaim my glory among the nations. 20 And they will bring all your brothers, from all the nations, to my holy mountain in Jerusalem as an offering to the LORD--on horses, in chariots and wagons, and on mules and camels," says the LORD. "They will bring them, as the Israelites bring their grain offerings, to the temple of the LORD in ceremonially clean vessels. 21 And I will select some of them also to be priests and Levites," says the LORD. 
22 "As the new heavens and the new earth that I make will endure before me," declares the LORD, "so will your name and descendants endure. 23 From one New Moon to another and from one Sabbath to another, all mankind will come and bow down before me," says the LORD. 24 "And they will go out and look upon the dead bodies of those who rebelled against me; their worm will not die, nor will their fire be quenched, and they will be loathsome to all mankind." 
(from New International Version)
 
 

Acts 28:16-28
16 When we got to Rome, Paul was allowed to live by himself, with a soldier to guard him.
17 Three days later he called together the leaders of the Jews. When they had assembled, Paul said to them: "My brothers, although I have done nothing against our people or against the customs of our ancestors, I was arrested in Jerusalem and handed over to the Romans.
18 They examined me and wanted to release me, because I was not guilty of any crime deserving death.
19 But when the Jews objected, I was compelled to appeal to Caesar-- not that I had any charge to bring against my own people.
20 For this reason I have asked to see you and talk with you. It is because of the hope of Israel that I am bound with this chain."
21 They replied, "We have not received any letters from Judea concerning you, and none of the brothers who have come from there has reported or said anything bad about you.
22 But we want to hear what your views are, for we know that people everywhere are talking against this sect."
23 They arranged to meet Paul on a certain day, and came in even larger numbers to the place where he was staying. From morning till evening he explained and declared to them the kingdom of God and tried to convince them about Jesus from the Law of Moses and from the Prophets.
24 Some were convinced by what he said, but others would not believe.
25 They disagreed among themselves and began to leave after Paul had made this final statement: "The Holy Spirit spoke the truth to your forefathers when he said through Isaiah the prophet:
26 "'Go to this people and say, "You will be ever hearing but never understanding; you will be ever seeing but never perceiving."
27 For this people's heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.'
28 "Therefore I want you to know that God's salvation has been sent to the Gentiles, and they will listen!"
(NIV)
 

Rom 16:25-27
25 Now to him who is able to establish you by my gospel and the proclamation of Jesus Christ, according to the revelation of the mystery hidden for long ages past,
26 but now revealed and made known through the prophetic writings by the command of the eternal God, so that all nations might believe and obey him--
27 to the only wise God be glory forever through Jesus Christ! Amen.
(NIV)
 
 

1 Cor 2:1-10
1 When I came to you, brothers, I did not come with eloquence or superior wisdom as I proclaimed to you the testimony about God.
2 For I resolved to know nothing while I was with you except Jesus Christ and him crucified.
3 I came to you in weakness and fear, and with much trembling.
4 My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit's power,
5 so that your faith might not rest on men's wisdom, but on God's power.
6 We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing.
7 No, we speak of God's secret wisdom, a wisdom that has been hidden and that God destined for our glory before time began.
8 None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory.
9 However, as it is written: "No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him"--
10 but God has revealed it to us by his Spirit. The Spirit searches all things, even the deep things of God.
(NIV)
 
 

2 Cor 4:1-4
1 Therefore, since through God's mercy we have this ministry, we do not lose heart.
2 Rather, we have renounced secret and shameful ways; we do not use deception, nor do we distort the word of God. On the contrary, by setting forth the truth plainly we commend ourselves to every man's conscience in the sight of God.
3 And even if our gospel is veiled, it is veiled to those who are perishing.
4 The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God.
(NIV)
 

Eph 3:1-12
1 For this reason I, Paul, the prisoner of Christ Jesus for the sake of you Gentiles--
2 Surely you have heard about the administration of God's grace that was given to me for you,
3 that is, the mystery made known to me by revelation, as I have already written briefly.
4 In reading this, then, you will be able to understand my insight into the mystery of Christ,
5 which was not made known to men in other generations as it has now been revealed by the Spirit to God's holy apostles and prophets.
6 This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus.
7 I became a servant of this gospel by the gift of God's grace given me through the working of his power.
8 Although I am less than the least of all God's people, this grace was given me: to preach to the Gentiles the unsearchable riches of Christ,
9 and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things.
10 His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms,
11 according to his eternal purpose which he accomplished in Christ Jesus our Lord.
12 In him and through faith in him we may approach God with freedom and confidence.
(NIV)
 
 

Col 1:23-29
23 if you continue in your faith, established and firm, not moved from the hope held out in the gospel. This is the gospel that you heard and that has been proclaimed to every creature under heaven, and of which I, Paul, have become a servant.
24 Now I rejoice in what was suffered for you, and I fill up in my flesh what is still lacking in regard to Christ's afflictions, for the sake of his body, which is the church.
25 I have become its servant by the commission God gave me to present to you the word of God in its fullness--
26 the mystery that has been kept hidden for ages and generations, but is now disclosed to the saints.
27 To them God has chosen to make known among the Gentiles the glorious riches of this mystery, which is Christ in you, the hope of glory.
28 We proclaim him, admonishing and teaching everyone with all wisdom, so that we may present everyone perfect in Christ.
29 To this end I labor, struggling with all his energy, which so powerfully works in me.
(NIV)
 
 

Rom 11:1-26
1 I ask then: Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin.
2 God did not reject his people, whom he foreknew. Don't you know what the Scripture says in the passage about Elijah-- how he appealed to God against Israel:
3 "Lord, they have killed your prophets and torn down your altars; I am the only one left, and they are trying to kill me"?
4 And what was God's answer to him? "I have reserved for myself seven thousand who have not bowed the knee to Baal."
5 So too, at the present time there is a remnant chosen by grace.
6 And if by grace, then it is no longer by works; if it were, grace would no longer be grace.
7 What then? What Israel sought so earnestly it did not obtain, but the elect did. The others were hardened,
8 as it is written: "God gave them a spirit of stupor, eyes so that they could not see and ears so that they could not hear, to this very day."
9 And David says: "May their table become a snare and a trap, a stumbling block and a retribution for them.
10 May their eyes be darkened so they cannot see, and their backs be bent forever."
11 Again I ask: Did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgression, salvation has come to the Gentiles to make Israel envious.
12 But if their transgression means riches for the world, and their loss means riches for the Gentiles, how much greater riches will their fullness bring!
13 I am talking to you Gentiles. Inasmuch as I am the apostle to the Gentiles, I make much of my ministry
14 in the hope that I may somehow arouse my own people to envy and save some of them.
15 For if their rejection is the reconciliation of the world, what will their acceptance be but life from the dead?
16 If the part of the dough offered as firstfruits is holy, then the whole batch is holy; if the root is holy, so are the branches.
17 If some of the branches have been broken off, and you, though a wild olive shoot, have been grafted in among the others and now share in the nourishing sap from the olive root,
18 do not boast over those branches. If you do, consider this: You do not support the root, but the root supports you.
19 You will say then, "Branches were broken off so that I could be grafted in."
20 Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but be afraid.
21 For if God did not spare the natural branches, he will not spare you either.
22 Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off.
23 And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again.
24 After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree!
25 I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in.
26 And so all Israel will be saved, as it is written: "The deliverer will come from Zion; he will turn godlessness away from Jacob.
(NIV)
 
 

Gen 12:1-3
1 The LORD had said to Abram, "Leave your country, your people and your father's household and go to the land I will show you.
2 "I will make you into a great nation and I will bless you; I will make your name great, and you will be a blessing.
3 I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you."
(NIV)
 

Gen 22:15-18
15 The angel of the LORD called to Abraham from heaven a second time
16 and said, "I swear by myself, declares the LORD, that because you have done this and have not withheld your son, your only son,
17 I will surely bless you and make your descendants as numerous as the stars in the sky and as the sand on the seashore. Your descendants will take possession of the cities of their enemies,
18 and through your offspring all nations on earth will be blessed, because you have obeyed me."
(NIV)
 

Eccl 3:10-11
10 I have seen the burden God has laid on men.
11 He has made everything beautiful in its time. He has also set eternity in the hearts of men; yet they cannot fathom what God has done from beginning to end.
(NIV)
 

Isa 29:10-14
10 The LORD has brought over you a deep sleep: He has sealed your eyes (the prophets); he has covered your heads (the seers).
11 For you this whole vision is nothing but words sealed in a scroll. And if you give the scroll to someone who can read, and say to him, "Read this, please," he will answer, "I can't; it is sealed."
12 Or if you give the scroll to someone who cannot read, and say, "Read this, please," he will answer, "I don't know how to read."
13 The Lord says: "These people come near to me with their mouth and honor me with their lips, but their hearts are far from me. Their worship of me is made up only of rules taught by men.
14 Therefore once more I will astound these people with wonder upon wonder; the wisdom of the wise will perish, the intelligence of the intelligent will vanish."
(NIV)
 

Isa 60:1-5
1 "Arise, shine, for your light has come, and the glory of the LORD rises upon you.
2 See, darkness covers the earth and thick darkness is over the peoples, but the LORD rises upon you and his glory appears over you.
3 Nations will come to your light, and kings to the brightness of your dawn.
4 "Lift up your eyes and look about you: All assemble and come to you; your sons come from afar, and your daughters are carried on the arm.
5 Then you will look and be radiant, your heart will throb and swell with joy; the wealth on the seas will be brought to you, to you the riches of the nations will come.
(NIV)

Matt 13:10-13
10 The disciples came to him and asked, "Why do you speak to the people in parables?"
11 He replied, "The knowledge of the secrets of the kingdom of heaven has been given to you, but not to them.
12 Whoever has will be given more, and he will have an abundance. Whoever does not have, even what he has will be taken from him.
13 This is why I speak to them in parables: "Though seeing, they do not see; though hearing, they do not hear or understand.
(NIV)
 

Matt 21:33-44
33 Hear another parable: There was a certain householder, which planted a vineyard, and hedged it round about, and digged a winepress in it, and built a tower, and let it out to husbandmen, and went into a far country:
34 And when the time of the fruit drew near, he sent his servants to the husbandmen, that they might receive the fruits of it.
35 And the husbandmen took his servants, and beat one, and killed another, and stoned another.
36 Again, he sent other servants more than the first: and they did unto them likewise.
37 But last of all he sent unto them his son, saying, They will reverence my son.
38 But when the husbandmen saw the son, they said among themselves, This is the heir; come, let us kill him, and let us seize on his inheritance.
39 And they caught him, and cast him out of the vineyard, and slew him.
40 When the lord therefore of the vineyard cometh, what will he do unto those husbandmen?
41 They say unto him, He will miserably destroy those wicked men, and will let out his vineyard unto other husbandmen, which shall render him the fruits in their seasons.
42 Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes?
43 Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof.
44 And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder.
(KJV)
 

Rom 3:1-31
1 What advantage, then, is there in being a Jew, or what value is there in circumcision?
2 Much in every way! First of all, they have been entrusted with the very words of God.
3 What if some did not have faith? Will their lack of faith nullify God's faithfulness?
4 Not at all! Let God be true, and every man a liar. As it is written: "So that you may be proved right when you speak and prevail when you judge."
5 But if our unrighteousness brings out God's righteousness more clearly, what shall we say? That God is unjust in bringing his wrath on us? (I am using a human argument.)
6 Certainly not! If that were so, how could God judge the world?
7 Someone might argue, "If my falsehood enhances God's truthfulness and so increases his glory, why am I still condemned as a sinner?"
8 Why not say-- as we are being slanderously reported as saying and as some claim that we say--" Let us do evil that good may result"? Their condemnation is deserved.
9 What shall we conclude then? Are we any better? Not at all! We have already made the charge that Jews and Gentiles alike are all under sin.
10 As it is written: "There is no one righteous, not even one;
11 there is no one who understands, no one who seeks God.
12 All have turned away, they have together become worthless; there is no one who does good, not even one."
13 "Their throats are open graves; their tongues practice deceit." "The poison of vipers is on their lips."
14 "Their mouths are full of cursing and bitterness."
15 "Their feet are swift to shed blood;
16 ruin and misery mark their ways,
17 and the way of peace they do not know."
18 "There is no fear of God before their eyes."
19 Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God.
20 Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin.
21 But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify.
22 This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference,
23 for all have sinned and fall short of the glory of God,
24 and are justified freely by his grace through the redemption that came by Christ Jesus.
25 God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished--
26 he did it to demonstrate his justice at the present time, so as to be just and the one who justifies those who have faith in Jesus.
27 Where, then, is boasting? It is excluded. On what principle? On that of observing the law? No, but on that of faith.
28 For we maintain that a man is justified by faith apart from observing the law.
29 Is God the God of Jews only? Is he not the God of Gentiles too? Yes, of Gentiles too,
30 since there is only one God, who will justify the circumcised by faith and the uncircumcised through that same faith.
31 Do we, then, nullify the law by this faith? Not at all! Rather, we uphold the law.
(NIV)
 

Rom 9:1-33
1 I speak the truth in Christ-- I am not lying, my conscience confirms it in the Holy Spirit--
2 I have great sorrow and unceasing anguish in my heart.
3 For I could wish that I myself were cursed and cut off from Christ for the sake of my brothers, those of my own race,
4 the people of Israel. Theirs is the adoption as sons; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises.
5 Theirs are the patriarchs, and from them is traced the human ancestry of Christ, who is God over all, forever praised! Amen.
6 It is not as though God's word had failed. For not all who are descended from Israel are Israel.
7 Nor because they are his descendants are they all Abraham's children. On the contrary, "It is through Isaac that your offspring will be reckoned."
8 In other words, it is not the natural children who are God's children, but it is the children of the promise who are regarded as Abraham's offspring.
9 For this was how the promise was stated: "At the appointed time I will return, and Sarah will have a son."
10 Not only that, but Rebekah's children had one and the same father, our father Isaac.
11 Yet, before the twins were born or had done anything good or bad-- in order that God's purpose in election might stand:
12 not by works but by him who calls-- she was told, "The older will serve the younger."
13 Just as it is written: "Jacob I loved, but Esau I hated."
14 What then shall we say? Is God unjust? Not at all!
15 For he says to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion."
16 It does not, therefore, depend on man's desire or effort, but on God's mercy.
17 For the Scripture says to Pharaoh: "I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth."
18 Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.
19 One of you will say to me: "Then why does God still blame us? For who resists his will?"
20 But who are you, O man, to talk back to God? "Shall what is formed say to him who formed it, 'Why did you make me like this?'"
21 Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?
22 What if God, choosing to show his wrath and make his power known, bore with great patience the objects of his wrath-- prepared for destruction?
23 What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory--
24 even us, whom he also called, not only from the Jews but also from the Gentiles?
25 As he says in Hosea: "I will call them 'my people' who are not my people; and I will call her 'my loved one' who is not my loved one,"
26 and, "It will happen that in the very place where it was said to them, 'You are not my people,' they will be called 'sons of the living God.'"
27 Isaiah cries out concerning Israel: "Though the number of the Israelites be like the sand by the sea, only the remnant will be saved.
28 For the Lord will carry out his sentence on earth with speed and finality."
29 It is just as Isaiah said previously: "Unless the Lord Almighty had left us descendants, we would have become like Sodom, we would have been like Gomorrah."
30 What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith;
31 but Israel, who pursued a law of righteousness, has not attained it.
32 Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the "stumbling stone."
33 As it is written: "See, I lay in Zion a stone that causes men to stumble and a rock that makes them fall, and the one who trusts in him will never be put to shame."
(NIV)

Rom 10:8-20
8 But what does it say? "The word is near you; it is in your mouth and in your heart," that is, the word of faith we are proclaiming:
9 That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved.
10 For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.
11 As the Scripture says, "Anyone who trusts in him will never be put to shame."
12 For there is no difference between Jew and Gentile-- the same Lord is Lord of all and richly blesses all who call on him,
13 for, "Everyone who calls on the name of the Lord will be saved."
14 How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them?
15 And how can they preach unless they are sent? As it is written, "How beautiful are the feet of those who bring good news!"
16 But not all the Israelites accepted the good news. For Isaiah says, "Lord, who has believed our message?"
17 Consequently, faith comes from hearing the message, and the message is heard through the word of Christ.
18 But I ask: Did they not hear? Of course they did: "Their voice has gone out into all the earth, their words to the ends of the world."
19 Again I ask: Did Israel not understand? First, Moses says, "I will make you envious by those who are not a nation; I will make you angry by a nation that has no understanding."
20 And Isaiah boldly says, "I was found by those who did not seek me; I revealed myself to those who did not ask for me."
(NIV)
 

Gal 3:6-29
6 Consider Abraham: "He believed God, and it was credited to him as righteousness."
7 Understand, then, that those who believe are children of Abraham.
8 The Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: "All nations will be blessed through you."
9 So those who have faith are blessed along with Abraham, the man of faith.
10 All who rely on observing the law are under a curse, for it is written: "Cursed is everyone who does not continue to do everything written in the Book of the Law."
11 Clearly no one is justified before God by the law, because, "The righteous will live by faith."
12 The law is not based on faith; on the contrary, "The man who does these things will live by them."
13 Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: "Cursed is everyone who is hung on a tree."
14 He redeemed us in order that the blessing given to Abraham might come to the Gentiles through Christ Jesus, so that by faith we might receive the promise of the Spirit.
15 Brothers, let me take an example from everyday life. Just as no one can set aside or add to a human covenant that has been duly established, so it is in this case.
16 The promises were spoken to Abraham and to his seed. The Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ.
17 What I mean is this: The law, introduced 430 years later, does not set aside the covenant previously established by God and thus do away with the promise.
18 For if the inheritance depends on the law, then it no longer depends on a promise; but God in his grace gave it to Abraham through a promise.
19 What, then, was the purpose of the law? It was added because of transgressions until the Seed to whom the promise referred had come. The law was put into effect through angels by a mediator.
20 A mediator, however, does not represent just one party; but God is one.
21 Is the law, therefore, opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, then righteousness would certainly have come by the law.
22 But the Scripture declares that the whole world is a prisoner of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe.
23 Before this faith came, we were held prisoners by the law, locked up until faith should be revealed.
24 So the law was put in charge to lead us to Christ that we might be justified by faith.
25 Now that faith has come, we are no longer under the supervision of the law.
26 You are all sons of God through faith in Christ Jesus,
27 for all of you who were baptized into Christ have clothed yourselves with Christ.
28 There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus.
29 If you belong to Christ, then you are Abraham's seed, and heirs according to the promise.
(NIV)
 
 

Eph 2:8-13
8 For it is by grace you have been saved, through faith-- and this not from yourselves, it is the gift of God--
9 not by works, so that no one can boast.
10 For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.
11 Therefore, remember that formerly you who are Gentiles by birth and called "uncircumcised" by those who call themselves "the circumcision" (that done in the body by the hands of men)--
12 remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world.
13 But now in Christ Jesus you who once were far away have been brought near through the blood of Christ.
(NIV)
 

Col 3:9-11
9 Do not lie to each other, since you have taken off your old self with its practices
10 and have put on the new self, which is being renewed in knowledge in the image of its Creator.
11 Here there is no Greek or Jew, circumcised or uncircumcised, barbarian, Scythian, slave or free, but Christ is all, and is in all.
(NIV)
 

1 Pet 1:10-13
10 Concerning this salvation, the prophets, who spoke of the grace that was to come to you, searched intently and with the greatest care,
11 trying to find out the time and circumstances to which the Spirit of Christ in them was pointing when he predicted the sufferings of Christ and the glories that would follow.
12 It was revealed to them that they were not serving themselves but you, when they spoke of the things that have now been told you by those who have preached the gospel to you by the Holy Spirit sent from heaven. Even angels long to look into these things.
13 Therefore, prepare your minds for action; be self-controlled; set your hope fully on the grace to be given you when Jesus Christ is revealed.
(NIV)
 
 

Rev 10:1-7
1 Then I saw another mighty angel coming down from heaven. He was robed in a cloud, with a rainbow above his head; his face was like the sun, and his legs were like fiery pillars.
2 He was holding a little scroll, which lay open in his hand. He planted his right foot on the sea and his left foot on the land,
3 and he gave a loud shout like the roar of a lion. When he shouted, the voices of the seven thunders spoke.
4 And when the seven thunders spoke, I was about to write; but I heard a voice from heaven say, "Seal up what the seven thunders have said and do not write it down."
5 Then the angel I had seen standing on the sea and on the land raised his right hand to heaven.
6 And he swore by him who lives for ever and ever, who created the heavens and all that is in them, the earth and all that is in it, and the sea and all that is in it, and said, "There will be no more delay!
7 But in the days when the seventh angel is about to sound his trumpet, the mystery of God will be accomplished, just as he announced to his servants the prophets."

Rev 21:22-27
22 I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple.
23 The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp.
24 The nations will walk by its light, and the kings of the earth will bring their splendor into it.
25 On no day will its gates ever be shut, for there will be no night there.
26 The glory and honor of the nations will be brought into it.
27 Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb's book of life.
(NIV)
