Deuteronomy 31:19-21

American Standard Version

¹⁹ Now therefore write ye this song for you, and teach thou it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel. ²⁰ For when I shall have brought them into the land which I sware unto their fathers, flowing with milk and honey, and they shall have eaten and filled themselves, and waxed fat; then will they turn unto other gods, and serve them, and despise me, and break my covenant. ²¹ And it shall come to pass, when many evils and troubles are come upon them, that this song shall testify before them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they frame this day, before I have brought them into the land which I sware.
