Deuteronomy 13:17-18

Keep not a thing of what is cursed for yourselves: so the Lord may be turned away from the heat of his wrath, and have mercy on you, and give you increase as he said in his oath to your fathers: So long as you give ear to the voice of the Lord your God, and keep all his orders which I give you today, and do what is right in the eyes of the Lord your God.
