Deuteronomy 12:29-31

29When the LORD thy God shall cut off the nations from before thee, where thou goest to possess them, and thou succeedest them, and dwellest in their land;1 30Take heed to thyself that thou be not snared by following them, after that they are 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.2 31Thou shalt not do so to the LORD thy God: for every abomination to the LORD, which he hateth, have they done to their gods; for even their sons and their daughters they have burnt in the fire to their gods.3
