Deuteronomy 12:30-31

30take heed to thyself that thou be not ensnared [to follow] after them, after that they are destroyed from before thee; and that thou inquire not after their 1gods, saying, How did these nations serve their 2gods? even so will I do likewise.

31Thou shalt not do so to Jehovah thy 3God; for every [thing that is] abomination to Jehovah, which he hateth, have they done unto their 4gods; for even their sons and their daughters have they burned in the fire to their 5gods.
