Deuteronomy 31:19-22

MSTC(i) 19 Now, therefore, write ye this song, and teach it the children of Israel and put it in their mouths — that this song may be my witness unto the children of Israel. 20 For when I have brought them into the land which I sware unto their fathers that runneth with milk and honey, then they will eat and fill themselves and wax fat and turn unto strange gods and serve them and rail on me and break my covenant. 21 And then, when much mischief and tribulation is come upon them, this song shall answer before them, and be a witness. It shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about even now before I have brought them into the land which I sware." 22 And Moses wrote this song the same season, and taught it the children of Israel.
