Deuteronomy 31:27-29

27I know how rebellious you are. You are impossible to deal with. While I am alive and still with you, you are rebelling against the Lord. How much more rebellious will you be after I die?

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.”
