Deuteronomy 31:27-29

27for I know thy rebellion, and thy stiff neck. Lo, while I am yet alive with you this day, ye have been rebellious against Jehovah; and how much more after my death!

28Gather to me all the elders of your tribes, and your officers, that I may speak these words in their ears, and take heaven and earth to witness against them.

29For I know that after my death ye will utterly corrupt yourselves, and will turn aside from the way which I have commanded you; and mischief will befall you at the end of days; because ye do evil in the sight of Jehovah, to provoke him to anger through the work of your hands.
