Deuteronomy 12:30-32

King James Version

³⁰ Take heed to thyself that thou be not snared by following them, after that they be destroyed from before thee; and that thou enquire not after their gods, saying, How did these nations serve their gods? even so will I do likewise.

³¹ Thou shalt not do so unto the Lord thy God: for every abomination to the Lord, which he hateth, have they done unto their gods; for even their sons and their daughters they have burnt in the fire to their gods.

³² What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it.
