Deuteronomy 12:29-31

29When the Lord your God eliminates the nations from the place where you are headed and you dispossess them, you will settle down in their land.

30After they have been destroyed from your presence, be careful not to be ensnared like they are; do not pursue their gods and say, “How do these nations serve their gods? I will do the same.”

31You must not worship the Lord your God the way they do! For everything that is abhorrent to him, everything he hates, they have done when worshiping their gods. They even burn up their sons and daughters before their gods!
