They will come on you in full measure In spite of your many sorceries, In spite of the great power of your spells. 10 "You felt secure in your wickedness and said, "No one sees me,' Your wisdom and your knowledge, they have deluded you; For you have said in your heart, "I am, and there is no one besides me.' 11 "But evil will come on you Which you will not know how to charm away; And disaster will fall on you For which you cannot atone; And destruction about which you do not know Will come on you suddenly. 12 "Stand fast now in your spells And in your many sorceries With which you have labored from your youth; Perhaps you will be able to profit, Perhaps you may cause trembling. 13 "You are wearied with your many counsels; Let now the astrologers, Those who prophesy by the stars, Those who predict by the new moons, Stand up and save you from what will come upon you. 14 "Behold, they have become like stubble, Fire burns them; They cannot deliver themselves from the power of the flame; There will be no coal to warm by Nor a fire to sit before! 15 "So have those become to you with whom you have labored, Who have trafficked with you from your youth; Each has wandered in his own way; There is none to save you.

He did much evil in the sight of the LORD, provoking Him to anger. 7 Then he put the carved image of the idol which he had made in the house of God, of which God had said to David and to Solomon his son, "In this house and in Jerusalem, which I have chosen from all the tribes of Israel, I will put My name forever; 8 and I will not again remove the foot of Israel from the land which I have appointed for your fathers, if only they will observe to do all that I have commanded them according to all the law, the statutes and the ordinances given through Moses." 9 Thus Manasseh misled Judah and the inhabitants of Jerusalem to do more evil than the nations whom the LORD destroyed before the sons of Israel.
