Deuteronomy 12:29-30

“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, 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?’
