John Gill Commentary 1 Chronicles 26

Concerning the divisions of the porters Or doorkeepers, whose business it was to open and shut the doors of the temple, to keep all impure and improper persons from entering into it, or any of the vessels being carried out of it, and to prevent tumults and riots about it; these, as it seems, David divided into a like number of classes, as the singers, to take their turns in waiting: of the Korhites was Meshelemiah the son of Kore, of the sons of Asaph; not Asaph the singer, who was a Gershonite, but the same with Eliasaph, (1 Chronicles 6:23 1 Chronicles 6:27) a Korhite.

Ver. 2,3. And the sons of Meshelemiah were, Zechariah the firstborn ,
&c.] And six more, who are mentioned in their order: Jediael, Zebadiah, and Jathniel, Elam, Jehohanan, and Elioenai .

(See Gill on 1 Chronicles 26:3)

Ver. 4,5. Moreover, the sons of Obededom The same at whose house the ark was, before it was brought by David to Zion; his sons were porters also, as himself, (1 Chronicles 15:24) (16:38), mention is made of eight sons of his, according to their birth:

Shemaiah, Jehozabad, Joah, Sacar, Nethaneel, Ammiel, Issachar, Peulthai; for God blessed him; as with wealth and riches, so with a numerous offspring, and that because of his entertainment of the ark at his house; the great increase of his family is aggravated by the Jews

FOOTNOTES:

• F17: beyond all credit, that all in his family brought eight at a birth; the Targum here makes them eighty two in all.
