Deuteronômio 31

19Now therefore write ye this song for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.
29For I know that after my death ye will utterly corrupt yourselves , and turn aside from the way which I have commanded you; and evil will befall you in the latter days; because ye will do evil in the sight of the LORD , to provoke him to anger through the work of your hands.
