Deuteronomy 12:28-30

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

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,

30beware 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?’
