Deuteronomy 12:29-32

You will enter the land and take it away from the nations that the LORD your God will destroy ahead of you. When you force them out and live in their land, they will be destroyed for you, but be careful not to be trapped by asking about their gods. Don’t say, “How do these nations worship? I will do the same.” Don’t worship the LORD your God that way, because the LORD hates the evil ways they worship their gods. They even burn their sons and daughters as sacrifices to their gods! Be sure to do everything I have commanded you. Do not add anything to it, and do not take anything away from it.
