Deuteronomy 31:24-28

²⁴It happened, when Moses had made an end of writing the words of this law in a book, until they were finished, ²⁵that Moses commanded the Levites, who bore the ark of the covenant of Yahweh, saying, ²⁶Take this book of the law, and put it by the side of the ark of the covenant of Yahweh your God, that it may be there for a witness against you. ²⁷For I know your rebellion, and your stiff neck: behold, while I am yet alive with you this day, you have been rebellious against Yahweh; and how much more after my death? ²⁸Assemble to me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to witness against them.
