Deuteronomy 12:28-30

28Observe and obey all these words which I command you, that it may go well with you and your children after you forever, when you do what is good and right in the sight of the Lord your God.

29“When the Lord your God cuts off from before you the nations which you go to dispossess, and you displace them and dwell in their land,

30take heed to yourself that you are not ensnared to follow them, after they are destroyed from before you, and that you do not inquire after their gods, saying, ‘How did these nations serve their gods? I also will do likewise.’
