All things being got ready for the carrying of the ark to the city of David, and its reception there, we have here an account of the solemnity of this conveyance thither from the house of Obed-edom.
I. God helped the Levites that carried it. The ark was no very great burden, that those who carried it needed any extraordinary help. But, 1. It is good to take notice of the assistance of the divine providence even in those things that fall within the compass of our natural powers: if God did not help us, we could not stir a step. 2. In all our religious exercises we must particularly derive help from heaven. See Act 26:22. All our sufficiency for holy duties is from God. 3. The Levites, remembering the breach upon Uzza, were probably ready to tremble when they took up the ark; but God helped them, that is, he encouraged them to it, silenced their fears, and strengthened their faith. 4. God helped them to do it decently and well, and without making any mistake. If we perform any religious duties so as to escape a breach, and come off with our lives, we must own it is God that helps us; for, if left to ourselves, we should be guilty of some fatal miscarriages. God's ministers that bear the vessels of the Lord have special need of divine help in their ministrations, that God in them may be glorified and his church edified. And, if God help the Levites, the people have the benefit of it.
II. When they experienced the tokens of God's presence with them they offered sacrifices of praise to him, Ch1 15:26. This also he helped them to do. They offered these bullocks and rams perhaps by way of atonement for the former error, that it might not now be remembered against them, as well as by way of acknowledgment for the help now received.
III. There were great expressions of rejoicing used: the sacred music was played, David danced, the singers sang, and the common people shouted, Ch1 15:27, Ch1 15:28. This we had before, Sa2 6:14, Sa2 6:15. Learn hence, 1. That we serve a good master, who delights to have his servants sing at their work. 2. That times of public reformation are, and should be, times of public rejoicing. Those are unworthy of the ark that are not glad of it. 3. It is not any disparagement to the greatest of men to show themselves zealous in the acts of devotion. Michal indeed despised David (Ch1 15:29); but her despising him did not make him at all despicable; he did not regard it himself, nor did any that were wise and good (and why should we covet the esteem of any but such?) think the worse of him.

A robe of fine linen - A robe made of בוץ buts, probably the tuft or beard of the Pinna Magna, a species of muscle found every where on the shores of the Mediterranean, growing sometimes, as I have seen, to a foot and a half in length. I have seen a pair of gloves made of this very rich stuff; the color is a deep dark yellow, something inclining to what is called the lilac. The buts or byssus was not heard of in Israel before the time of David: after that it is frequently mentioned.

Thus all Israel brought up the ark of the covenant of the Lord with shouting,.... See Sa2 6:15.
1 Chronicles 15:29

a robe of fine linen--Hebrew, Butz--is rather supposed in the later books to denote cotton.

an ephod--a shoulder-garment, a cincture or cape over his dress. It was worn by the priests, but was not so peculiar to them as to be forbidden others (Sa1 2:18; Sa1 22:18).
