Deuteronomy 29:16-20

(for you know how we lived in the land of Egypt, and how we came through the midst of the nations through which you passed; moreover, you have seen their abominations and their idols of wood, stone, silver, and gold, which they had with them); so that there will not be among you a man or woman, or family or tribe, whose heart turns away today from the LORD our God, to go and serve the gods of those nations; that there will not be among you a root bearing poisonous fruit and wormwood. It shall be when he hears the words of this curse, that he will boast, saying, ‘I have peace though I walk in the stubbornness of my heart in order to destroy the watered land with the dry.’ The LORD shall never be willing to forgive him, but rather the anger of the LORD and His jealousy will burn against that man, and every curse which is written in this book will rest on him, and the LORD will blot out his name from under heaven.
