Deuteronomy 29:16

14Neither do I make this covenant and this oath with you only,

15but with those who stand here with us today before the LORD our God, and also with those who are not here with us today

16(for you know how we lived in the land of Egypt, and how we came through the middle of the nations through which you passed;

17and you have seen their abominations and their idols of wood, stone, silver, and gold, which were among them);

18lest there should be among you man, woman, family, or tribe whose heart turns away today from the LORD our God, to go to serve the gods of those nations; lest there should be among you a root that produces bitter poison;
