Deuteronomy 31:19-20

“So write down the words of this song, and teach it to the people of Israel. Help them learn it, so it may serve as a witness for me against them. For I will bring them into the land I swore to give their ancestors—a land flowing with milk and honey. There they will become prosperous, eat all the food they want, and become fat. But they will begin to worship other gods; they will despise me and break my covenant.
