Deuteronomy 31:19–26

19 “Now therefore write mthis song and nteach it to the people of Israel. Put it in their mouths, that this song may be oa witness for me against the people of Israel. 20 For when I have brought them into the land pflowing with milk and honey, which I swore to give to their fathers, and they have eaten and are full and qgrown fat, rthey will turn to other gods and serve them, and sdespise me and gbreak my covenant. 21 And when many evils and troubles have come upon them, this song shall confront them as ta witness (for it will live unforgotten in the mouths of their offspring). For uI know what they are inclined to do even today, 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 vAnd the Lord1 commissioned Joshua the son of Nun and said, w“Be strong and courageous, for you shall bring the people of Israel into the land that I swore to give them. xI will be with you.”

24 When Moses had finished ywriting the words of this law in a book to the very end, 25 Moses commanded zthe Levites who carried the ark of the covenant of the Lord, 26 “Take this Book of the Law aand put it by the side of the ark of the covenant of the Lord your God, that it may be there for ba witness against you.
