Deuteronomy 29:18

Deuteronomy 29:18. Lest there should be among you man, or woman, or family, or tribe, whose heart turneth away this day from the LORD our God, to go and serve the gods of these nations; lest there should be among you a root that beareth gall and wormwood;

For the worship of false gods is the cause of untold mischief and evil: wherever it is found it is a root that beareth gall and wormwood, and God would not have it in a single individual, man nor woman, nay, not in a single family or tribe.
