Deuteronomy 12:29-32

Leeser(i) 29 When the Lord thy God will cut off the nations, whither thou goest to drive them out from before thee, and thou succeedest them, and dwellest in their land: 30 Then take heed to thyself that thou be not snared by following them, after they have been destroyed from before thee; and that thou inquire 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 have they burnt in the fire to their gods. 32 (13:1) What thing soever I command you, even that shall ye observe to do: thou shalt not add thereto, and thou shalt not diminish therefrom.
