Deuteronomy 12:30-32

Good News Translation

³⁰ After the Lord destroys those nations, make sure that you don't follow their religious practices, because that would be fatal. Don't try to find out how they worship their gods, so that you can worship in the same way. ³¹ Do not worship the Lord your God in the way they worship their gods, for in the worship of their gods they do all the disgusting things that the Lord hates. They even sacrifice their children in the fires on their altars.

^32 (A)“Do everything that I have commanded you; do not add anything to it or take anything from it.
