Deuteronomy 31:19-22

CLV(i) 19 And now, write down for yourselves this song and teach it to the sons of Israel. Put it in their mouths so that this song may come to be for Me as a testimony against the sons of Israel. 20 When I shall bring them to the ground gushing with milk and honey about which I had sworn to their fathers, when they eat and are satisfied and are sleek so that they turn around to other elohim and serve them, when they thus spurn Me and annul My covenant, 21 and it comes to be that many evils and distresses find them, then this song will answer as a testimony before them (for it shall not be forgotten from the mouths of their seed) that I know the bent of their heart which they are forming today ere I bring them to the land about which I had sworn. 22 (Moses wrote this song on that day and taught it to the sons of Israel.)
