I Chronicles 15:4

And David assembled the children of Aaron, and the Levites. Whose business it was to bear the ark when there was any occasion for it: and from hence to the end of Ch1 15:10 an account is given of the Levites, and their number employed in this affair: of the sons of Kohath; a son of Levi, that is, of his posterity; for his immediate sons, and so those of the rest after mentioned, had been dead ages ago; the principal of those, at this present time, was Uriel, and his kindred, or those of the same family with him, were one hundred and twenty: of those of Merari, another son of Levi, the chief was Asaiah, with two hundred and twenty of his relations: of those of Gershon, another son of Levi, was Joel, and his brethren were one hundred and thirty: of the posterity of Elizaphan, a grandson of Kohath, Exo 5:18, the most noted was Shemaiah, who had two hundred of his family with him: and of those of Hebron, the son of Kohath, Exo 6:18, Eliel was the most famous, and he had eighty of his kindred with him: and of those of Uzziel, another son of Kohath in a different line from Elizaphan, who also was a son of Uzziel, was Amminadab the chief, who had one hundred and twelve of his kindred with him: the number of Levites, in all, gathered together, were eight hundred and sixty two, besides their chiefs.

The bringing in of the ark to the city of David was a very good work; it was resolved upon (Ch1 13:4), and attempted, but not perfected; it lay by the way in the house of Obed-edom. Now this chapter gives us an account of the completing of that good work. I. How it was done more regularly than before. 1. A place was prepared for it (Ch1 15:1). 2. The priests were ordered to carry it (Ch1 15:2-15). 3. The Levites had their offices assigned them in attending on it (Ch1 15:16-24). II. How it was done more successfully than before (Ch1 15:25). 1. The Levites made no mistake in their work (Ch1 15:26). 2. David and the people met with no damp upon their joy (Ch1 15:27, Ch1 15:28). As for Michal's despising David, it was nothing (Ch1 15:29).
