Deuteronomy 31:21-23

New Revised Standard Version Catholic Edition

²¹ And when many terrible troubles come upon them, this song will confront them as a witness, because it will not be lost from the mouths of their descendants. For I know what they are inclined to do even now, before I have brought them into the land that I promised them on oath.” ²² That very day Moses wrote this song and taught it to the Israelites.

²³ Then the Lord commissioned Joshua son of Nun and said, “Be strong and bold, for you shall bring the Israelites into the land that I promised them; I will be with you.”
