Deuteronomy 31:19-20

“Now then, write this song for yourselves, and teach it to the sons of Israel; put it in their mouth, so that this song may be a witness for Me against the sons of Israel. For when I bring them into the land which I have sworn to their fathers, a land [of plenty] flowing with milk and honey, and they have eaten and are satisfied and become prosperous, then they will turn to other gods and serve them, and despise and reject Me and break My covenant.
