Deuteronomy 31:28-30

28Assemble unto me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to witness against them. 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 that which is evil in the sight of Jehovah, to provoke him to anger through the work of your hands.

30And Moses spake in the ears of all the assembly of Israel the words of this song, until they were finished.
