Deuteronomy 8:19-20

Amplified Bible

¹⁹ And it shall come about if you ever forget the Lord your God and follow other gods and serve them and worship them, I testify against you today that you will most certainly perish. ²⁰ Like the nations which the Lord causes to perish before you, so shall you perish; because you would not listen to and obey the voice of the Lord your God.
