1 Chronicles 9:17

And the porters were, Shallum, and Akkub, and Talmon, and Ahiman. — Comp. Nehemiah 11:18, which sums up thus: “All the Levites in the holy city were two hundred fourscore and four. Moreover the porters, Akkub, Talmon, and their brethren that kept the gates, were an hundred seventy and two.” Shallum does not appear.

Ahiman may have originated out of the following:

Their brethren. — Heb., aheihem. Comp. also Nehemiah 12:25, where we are told that (Mattaniah and Bakbukiah, Obadiah and) Meshullam (i.e., Shallum), Talmon, and Akkub were porters keeping ward at the storehouses of the Temple gates, in the times of Joiakim son of Jeshua son of Jozadak, and of Nehemiah and Ezra. It is clear that the names of the porters likewise represent families or guilds, which had hereditary charge of the Temple gates. In fact, all the Levitical functions appear to have descended in the same families from father to son, like the various civil offices in the Roman empire; and tradition ascribed the entire arrangement to David, the second founder of the national worship. At this point the correspondence with Nehemiah 11 ceases.

Shallum was the chief. — This really belongs to 1 Chronicles 9:18, and introduces a description of the duties of the Levites, which extends over 1 Chronicles 9:18. Translate, Shallum is the chief even unto this day in the king’s gate, on the east side. Shallum (“recompense”) is called “Shelemiah” (1 Chronicles 26:14), which, again, is a curtailment of Meshelemiah (“Jah recompenseth”), 1 Chronicles 26:1; 1 Chronicles 9:21 infra. The fact that Shallum — Meshelemiah — is spoken of as warder in David’s day as well as in the post-exilic age, proves that a guild or clan, not an individual, is in question. The eastern gate was the post of honour (Ezekiel 46:1), and the royal entry. The old name of the King’s Gate would naturally be retained in the restored Temple.
