9 Next to them repaired Rephaiah the son of Hur, the ruler of half the district of Jerusalem.

Ruler of the half part of Jerusalem - Probably the city was divided into two parts; one for Judah, and the other for Benjamin, each having its proper governor. Rephaiah mentioned here was one of these governors, and Shallum, mentioned Nehemiah 3:12, was the other. There were other rulers or governors of particular country or village districts.
And next unto them repaired Rephaiah, the son of Hur, the ruler of the half part of Jerusalem. That city belonging partly to the tribe of Judah, and partly to the tribe of Benjamin; one part of it was under a governor that was of the tribe of Judah, as this man seems to be; and the other part under one of the tribe of Benjamin; see Nehemiah 3:12.
Half part - As Rome was anciently divided into several quarters or regions, so was Jerusalem; and especially into two parts, whereof one was in the tribe of Benjamin, and nearest the temple, the other in the tribe of Judah, these accordingly had two several rulers, this man and the other, Nehemiah 3:12, but both under the chief governor of the city.
