Deuteronomy 31:21-23

Revised Standard Version

²¹ And when many evils and troubles have come upon them, this song shall confront them as a witness (for it will live unforgotten in the mouths of their descendants); for I know the purposes which they are already forming, before I have brought them into the land that I swore to give.” ²² So Moses wrote this song the same day, and taught it to the people of Israel.

²³ And the Lord commissioned Joshua the son of Nun and said, “Be strong and of good courage; for you shall bring the children of Israel into the land which I swore to give them: I will be with you.”
