Deuteronomy 31:19-21

“But for right now, copy down this song and teach the People of Israel to sing it by heart. They’ll have it then as my witness against them. When I bring them into the land that I promised to their ancestors, a land flowing with milk and honey, and they eat and become full and get fat and then begin fooling around with other gods and worshiping them, and then things start falling apart, many terrible things happening, this song will be there with them as a witness to who they are and what went wrong. Their children won’t forget this song; they’ll be singing it. Don’t think I don’t know what they are already scheming to do, and they’re not even in the land yet, this land I promised them.”
