Deuteronomy 12:28-32

28“Be careful and listen to all these words which I am commanding you, so that 1it may go well for you and your sons after you forever, for you will be doing what is good and right in the sight of the Lord your God.

29“When 2the 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 3to 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?’ 314You 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 5they even burn their sons and daughters in the fire for their gods.

32“67Whatever I command you, you shall be careful to do; 8you shall not add to nor take anything away from it.
