Deuteronomy 12:28-30

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?’
