Deuteronomy 31:18

14 Then the LORD said to Moses, “Behold, the time of your death is near. Call Joshua and present yourselves at the Tent of Meeting, so that I may commission him.” So Moses and Joshua went and presented themselves at the Tent of Meeting.

15 Then the LORD appeared at the tent in a pillar of cloud, and the cloud stood over the entrance to the tent.

16 And the LORD said to Moses, “You will soon rest with your fathers, and these people will rise up and prostitute themselves with the foreign gods of the land they are entering. They will forsake Me and break the covenant I have made with them.

17 On that day My anger will burn against them, and I will abandon them and hide My face from them, so that they will be consumed, and many troubles and afflictions will befall them. On that day they will say, ‘Have not these disasters come upon us because our God is no longer with us?’

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.
