Deuteronomy 31:15-21

151The Lord appeared in the tent in a pillar of cloud, and the pillar of cloud stood at the doorway of the tent. 16The Lord said to Moses, “Behold, 2you are about to lie down with your fathers; and 3this people will arise and play the harlot with the strange gods of the land, into the midst of which they are going, and 4will forsake Me and break My covenant which I have made with them. 175Then My anger will be kindled against them in that day, and 6I will forsake them and 7hide My face from them, and they will be consumed, and many evils and troubles will come upon them; so that they will say in that day, ‘8Is it not because our God is not among us that these evils have come upon us?’ 18But I will surely hide My face in that day because of all the evil which they will do, for they will turn to other gods.

19“Now therefore, 9write this song for yourselves, and teach it to the sons of Israel; put it 10on their lips, so that this song may be a witness for Me against the sons of Israel. 2011For when I bring them into the land flowing with milk and honey, which I swore to their fathers, and they have eaten and are satisfied and 12become 13prosperous, then they will turn to other gods and serve them, and spurn Me and break My covenant. 21Then it shall come about, 14when many evils and troubles have come upon them, that this song will testify before them as a witness (for it shall not be forgotten from the 15lips of their descendants); for 16I know their intent which they are 17developing today, before I have brought them into the land which I swore.”
