Deuteronomy 8:19 – 20
New International Version (NIV)
19 If you ever forget the LORD your God and follow other gods and worship and bow down to them, I testify against you today that you will surely be destroyed. 20 Like the nations the LORD destroyed before you, so you will be destroyed for not obeying the LORD your God.
