Deuteronomy 31:21  (King James Version)
And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for 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.

this song
A sacred song, appointed to be composed by Moses, doubtless under divine inspiration; which the people were required to learn, and teach to their children from generation to generation.
