Deuteronomy 31:25

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.

27 For I know how rebellious and stiff-necked you are. If you are already rebelling against the LORD while I am still alive, how much more will you rebel after my death!

28 Assemble before me all the elders of your tribes and all your officers so that I may speak these words in their hearing and call heaven and earth to witness against them.

29 For I know that after my death you will become utterly corrupt and turn from the path I have commanded you. And in the days to come, disaster will befall you because you will do evil in the sight of the LORD to provoke Him to anger by the work of your hands.”
