Deuteronomy 31:26-28

26“Take this Book of the Law and place it beside the ark of the covenant of the LORD your God. There it will remain as a witness against you. 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.
