Deuteronomy 31:28-29

28“Now summon all the elders and officials of your tribes, so that I can speak to them directly and call heaven and earth to witness against them.

29I know that after my death you will become utterly corrupt and will turn from the way I have commanded you to follow. In the days to come, disaster will come down on you, for you will do what is evil in the Lord’s sight, making him very angry with your actions.”
