Deuteronomy 31:27-29

27For I know how rebellious and stiff-necked you are. If you have been rebellious against the Lord while I am still alive and with you, how much more will you rebel after I die!

28Assemble before me all the elders of your tribes and all your officials, so that I can speak these words in their hearing and call the heavens and the earth to testify against them.

29For I know that after my death you are sure to become utterly corrupt and to turn from the way I have commanded you. In days to come, disaster will fall on you because you will do evil in the sight of the Lord and arouse his anger by what your hands have made.”
