Deuteronomy 12:29-31

29“When 1the Lord your God cuts off from you the nations which you are going in to dispossess, and you dispossess them and live in their land, 30be careful that you are not ensnared 2to follow them, after they are destroyed from your presence, and that you do not inquire about their gods, saying, ‘How do these nations serve their gods, that I also may do likewise?’ 313You shall not behave this way toward the Lord your God, because every abominable act which the Lord hates, they have done for their gods; for 4they even burn their sons and daughters in the fire for their gods.
