Deuteronomy 12:28-30

28Take care and listen to all these words that I am commanding you, so that it may go well with you and your children after you forever, when you do what is good and right in the eyes of Adonai your God.

29“When Adonai your God cuts off before you the nations that you are going in to dispossess, when you have dispossessed them and settled in their land,

30be careful not to be trapped into imitating them after they have been destroyed before you. Do not inquire about their gods, saying, ‘How do these nations serve their gods? I will do the same.’
