I Chronicles 15:18

And with them their brethren of the second degree,.... Who were next unto them, both in office and skill in singing: the fourteen following, Zechariah, Ben, and Jaaziel, and Shemiramoth, and Jehiel, and Unni, Eliab, and Benaiah, and Maaseiah, and Mattithiah, and Elipheleh, and Mikneiah, and Obededom, and Jeiel, the porters; who, when they were not employed in singing, were doorkeepers of the sanctuary; either they had been porters at the tabernacle in Gibeon, or were so after the ark was placed in the tabernacle David prepared for it.

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).
