Neh 12:24

“Mattaniah, and Bakbukiah, Obadiah, Meshullam, Talmon, Akkub, were porters,.... At the gates of the temple, see Ch1 9:15, keeping the ward, at the thresholds of the gates; of the temple, where they stood and watched; or "at the collection of the gates", meaning either where the people were gathered together, or where money gathered was laid up; and so some render it, "the treasuries of the gates": unless a place called Asuppim should be meant, Ch1 26:15.”

“The names Hashabiah, Sherebiah, Jeshua, and Kadmiel, frequently occur as those of heads of Levitical orders: the two first in Neh 10:12., Ezr 8:18.; the two last in Neh 12:8, Neh 10:10, and Ezr 2:40; and the comparison of these passages obliges us to regard and expunge as a gloss the בּן before Kadmiel. Opposite to these four are placed their brethren, whose office it was "to praise (and) to give thanks according to the commandment of David," etc.: comp. Ch1 16:4; Ch1 23:30; Ch2 5:13; and בּמצות ד, Ch2 29:25. משׁמר לעמּת משׁמר, ward opposite ward, elsewhere used of the gatekeepers, Ch1 26:16, is here applied to the position of the companies of singers in divine worship. The names of the brethren, i.e., of the Levitical singers, follow, Neh 12:25, where the first three names must be separated from those which follow, and combined with Neh 12:24. This is obvious from the consideration, that Mattaniah and Bakbukiah are mentioned in Neh 11:17 as presidents of two companies of singers, and with them Abda the Jeduthunite, whence we are constrained to suppose that עבדיה is only another form for עבדּא of Neh 11:17. According, then, to what has been said, the division into verses must be changed, and Neh 12:25 should begin with the name משׁלּם. Meshullam, Talmon, and Akkub are chiefs of the doorkeepers; the two last names occur as such both in Neh 11:19 and Ezr 2:42, and even so early as Ch1 9:17, whence we perceive that these were ancient names of races of Levitical doorkeepers. In Ezr 2:42 and Ch1 9:17, שׁלוּם, answering to משׁלּם of the present verse, is also named with them. The combination משׁמר שׁוערים שׁמרים is striking: we should at least have expected משׁמר שׁמרים שׁוערים, because, while שׁוערים cannot be combined with משׁמר, שׁמרים may well be so; hence we must either transpose the words as above, or read according to Neh 11:19, בּשּׁערים שׁמרים. In the latter case, בּשּׁערים is more closely defined by the apposition השּׁערים בּאספּי: at the doors, viz., at the treasure-chambers of the doors. On 'acupiym, see rem. on Ch1 26:15, Ch1 26:17.”
