Deuteronomy 31:21-23

International Standard Version

²¹ Then, when many evils and troubles will have come upon them, this song will serve as a witness against them, since their descendants won’t fail to sing it. I know the plan that they are devising even before I bring them into the land that I promised them^[a] by an oath.”

²² So Moses wrote the song that very day and taught it to the Israelis. ²³ Then the Lord charged Nun’s son Joshua, “Be strong and courageous, because you’ll bring the Israelis to the land that I promised to them by an oath. I’ll be with you.”
