Deuteronomy 29:17-20

17And ye have seen their abominations, and their idols, wood and stone, silver and gold, which were among them:)1

18Lest there should be among you man, or woman, or family, or tribe, whose heart turneth away this day from Yhwh our God, to go and serve the gods of these nations; lest there should be among you a root that beareth gall and wormwood;2

19And it come to pass, when he heareth the words of this curse, that he bless himself in his heart, saying, I shall have peace, though I walk in the imagination of mine heart, to add drunkenness to thirst:34

20Yhwh will not spare him, but then the anger of Yhwh and his jealousy shall smoke against that man, and all the curses that are written in this book shall lie upon him, and Yhwh shall blot out his name from under heaven.
