Deuteronomy 31:15-21

151And the Lord appeared in the tent in a pillar of cloud, and the pillar of cloud stood at the entrance of the tent. 16The Lord said to Moses, “Behold, 2you are about to 3lie down with your fathers; and 4this people will arise and play the prostitute with the foreign gods of the land into the midst of which they are going, and 5they will abandon Me and break My covenant which I have made with them. 176Then My anger will be kindled against them on that day, and 7I will abandon them and 8hide My face from them, and they will be consumed, and many evils and troubles will find them; so they will say on that day, ‘9Is it not because our God is not among us that these evils have found us?’ 18But I will assuredly hide My face on that day because of all the evil that they will have done, for they will have turned away to other gods.

19“Now then, 10write this song for yourselves, and teach it to the sons of Israel; put it 11on their lips, so that this song may be a witness for Me against the sons of Israel. 2012For when I bring them into the land flowing with milk and honey, which I swore to their fathers, and they eat and are satisfied and 13become 14prosperous, then they will turn to other gods and serve them, and spurn Me and break My covenant. 21Then it will come about, 15when many evils and troubles find them, that this song will testify before them as a witness (for it shall not be forgotten from the mouth of their 16descendants); for 17I know their inclination which they are 18developing today, before I bring them into the land which I swore.”
