Verse 21. - This and the following two verses give the houses of Merari, contributing four houses, and, with the nine Gershonite and eleven Kohathite, adding up to twenty-four. Merari is the third son of Levi (Genesis 46:11). The Mahli and Mushi of this verse were possibly grandson and son of Merari, if we follow the guidance of 1 Chronicles 6:47. Yet it would seem far more natural to explain this last-quoted passage by our ver. 23, which would then parallel it. Otherwise we must account for the name of Mahli habitually standing first, as here, as in 1 Chronicles 6:19 also, and 1 Chronicles 24:26, as also in Exodus 6:19; Numbers 3:20, 33, etc.; in all of which places the statement is as distinct as in this verse, that Mahli and Mushi were sons. This and the following verse must be compared particularly with 1 Chronicles 24:26-29; the Jaaziah of which passage was evidently no son of Merari, on a par with Mahli and Mushi, but a later descendant. His descendants were three - Shoham, Zaccur, and Ibri (Beno being no proper name, but signifying "his son").
23:1-23 David, having given charge concerning the building of the temple, settles the method of the temple service, and orders the officers of it. When those of the same family were employed together, it would engage them to love and assist one another.
