John Gill, on Neh 3:14

“And the gate of the dunghill Melchias the son of Rechab built, lord of the street of Bethacharam: he built it, and set up the doors thereof, and the locks, and the bars.”

“But the gate of the fountain,.... Of which see Neh 2:14 repaired Shallum, the son of Colhozeh, the ruler of part of Mizpah; of a tract, district, town, or city so called; perhaps that in the tribe of Benjamin; see Neh 3:7, he built it, and covered it; roofed it, which is not said of any of the other gates, whether because of the fountain at it: and set up the doors thereof, &c. finished it completely: and the wall of the pool of Siloah, by the king's garden; which was formerly without the wall, on the west, but afterwards taken in by Manasseh, who built it; see Ch2 33:14, and from hence the king's garden was watered: and unto the stairs that go down from the city of David: Zion, which was built on an eminence, from which they went down by steps into the lower city Acra.”
