Deuteronomy 31:20-22

New Century Version

²⁰ When I bring them into the land I promised to their ancestors, a fertile land, they will eat as much as they want and get fat. Then they will turn to other gods and serve them. They will reject me and break my Agreement. ²¹ Then when many troubles and terrible things happen to them, this song will testify against them, because the song will not be forgotten by their descendants. I know what they plan to do, even before I take them into the land I promised them.” ²² So Moses wrote down the song that day, and he taught it to the Israelites.
