Deuteronomy 12:29-32

Amplified Bible

²⁹ “When the Lord your God cuts off and destroys before you the nations which you are going in to dispossess, and you dispossess them and settle in their land, ³⁰ beware that you are not lured (ensnared) into following them, after they have been destroyed before you, and that you do not inquire about their gods, saying, ‘How did these nations serve their gods, so that I too may do likewise?’ ³¹ You shall not behave this way toward the Lord your God, for they have done for their gods every repulsive thing which the Lord hates; for they even burn their sons and their daughters in the fire [as sacrifices] to their gods.

³² “Everything I command you, you shall be careful to do it; you shall not add to it nor take away from it.
