Deuteronomy 31:21-23

Complete Jewish Bible

²¹ then, after many calamities and troubles have come upon them, this song will testify before them as a witness, because their descendants will still be reciting it and will not have forgotten it. For I know how they think even now, even before I have brought them into the land about which I swore.” ²² So Moshe wrote this song that same day and taught it to the people of Isra’el.

²³ Adonai also commissioned Y’hoshua the son of Nun with these words: “Be strong and full of courage; for you are to bring the people of Isra’el into the land about which I swore to them; and I will be with you.”
