Deuteronomy 31:20-21

20For after I have brought them to the land I promised to their ancestors – one flowing with milk and honey – and they eat their fill and become fat, then they will turn to other gods and worship them; they will reject me and break my covenant.

21Then when many disasters and distresses overcome them this song will testify against them, for their descendants will not forget it. I know the intentions they have in mind today, even before I bring them to the land I have promised.”
