Deuteronomy 31:22

18 And on that day I will surely hide My face because of all the evil they have done by turning to other gods.

19 Now therefore, write down for yourselves this song and teach it to the Israelites; have them recite it, so that it may be a witness for Me against them.

20 When I have brought them into the land that I swore to give their fathers, a land flowing with milk and honey, they will eat their fill and prosper. Then they will turn to other gods and worship them, and they will reject Me and break My covenant.

21 And when many troubles and afflictions have come upon them, this song will testify against them, because it will not be forgotten from the lips of their descendants. For I know their inclination, even before I bring them into the land that I swore to give them.”

22 So that very day Moses wrote down this song and taught it to the Israelites.

23 Then the LORD commissioned Joshua son of Nun and said, “Be strong and courageous, for you will bring the Israelites into the land that I swore to give them, and I will be with you.”

24 When Moses had finished writing in a book the words of this law from beginning to end,

25 he gave this command to the Levites who carried the ark of the covenant of the LORD:

26 “Take this Book of the Law and place it beside the ark of the covenant of the LORD your God, so that it may remain there as a witness against you.
