Deuteronomy 12:30-31

take heed to thyself that thou be not ensnared to follow them, after that they are destroyed from before thee; and that thou inquire not after their gods, saying, How do these nations serve their gods? even so will I do likewise. Thou shalt not do so unto Jehovah thy God: for every abomination to Jehovah, which he hateth, have they done unto their gods; for even their sons and their daughters do they burn in the fire to their gods.
