Deuteronomy 31:28-29

28Assemble all the leaders of your tribes and your officers in front of me. As they listen, I will speak these words and call on heaven and earth to testify against them.

29I know that after I die you will become thoroughly corrupt and turn from the way I have commanded you to live. In the days to come disasters will happen to you because you will make the Lord furious by doing what he considers evil.”
