The Levites, which bare the ark - i. e., as in Deuteronomy 31:9, "the priests the sons of Levi." The non-priestly Levites could not so much as enter the sanctuary or touch the ark (compare Numbers 4:15). Though in the journeys through the wilderness the ark was borne by the non-priestly Kohathites, yet on occasions of a more solemn and public character it was carried by the priests themselves (Joshua 3:3 ff, Joshua 4:9-10; Joshua 6:6, Joshua 6:12; Joshua 8:33; 1 Kings 8:3).

That Moses commanded the Levites,.... These were not the common Levites, but the priests who were also Levites, to whom the law was given, Deuteronomy 31:9; and none but they might touch the ark, or go so near it as, they are bid to do, to put the law on the side of it; so Aben Ezra; it follows:

which bare the ark of the covenant of the Lord; as the priests are said to do; see Gill on Deuteronomy 31:9; for though in journeying the Kohathites carried it, yet not until it was covered by the priests, for they must not touch it; as these must do when they put the law on the side of it, as they are ordered in Deuteronomy 31:26.

saying; as follows.

That Moses commanded the Levites, which bare the ark of the covenant of the LORD, saying,

31:25 The Levites - The priests, Deu 31:9, who also were Levites.

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.
