Deuteronomy 29:17-19

Young's Literal Translation

¹⁷ and ye see their abominations, and their idols, wood and stone, silver and gold, which [are] with them,

¹⁸ lest there be among you a man or woman, or family or tribe, whose heart is turning to-day from Jehovah our God, to go to serve the gods of those nations, lest there be in you a root fruitful of gall and wormwood:

¹⁹ `And it hath been, in his hearing the words of this oath, and he hath blessed himself in his heart, saying, I have peace, though in the stubbornness of my heart I go on, in order to end the fulness with the thirst.
