Deuteronomy 8:19-20

New Catholic Bible

¹⁹ But if you forget the Lord, your God, and follow after other gods, serving and worshiping them, then I swear to you today that you will surely perish. ²⁰ You will perish just like the nations that the Lord crushed in your sight, for you would not have been attentive to the voice of the Lord, your God.
