24 It happened, when Moses had made an end of writing the words of this law in a book, until they were finished, 25 that Moses commanded the Levites, who bore the ark of the covenant of Yahweh, saying, 26 “Take 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.

Commentary on Deuteronomy 31:23-30
(Read Deuteronomy 31:23-30)
The solemn delivery of the book of the law to the Levites, to be deposited in, or rather by the side, of the ark, is again related. The song which follows in the next chapter is delivered to Moses, and by him to the people. He wrote it first, as the Holy Spirit taught him; and then spake it in the hearing of all the people. Moses tells them plainly, I know that after my death ye will utterly corrupt yourselves. Many a sad thought, no doubt, it occasioned to this good man; but his comfort was, that he had done his duty, and that God would be glorified in their dispersion, if not in their settlement, for the foundation of God stands sure.
