Now after this he built a wall without the city of David
Which perhaps had been broken down by the Assyrian army, when it came and took him; Vitringa F12 thinks this is the wall of the pool of Siloah, ( Nehemiah 3:15 ) which seems to be the first and oldest wall, as Josephus F13; for that turning to the north bent towards the pool of Siloam; an Arabic writer F14 calls it the southern wall:
on the west side of Gihon;
on the west side of the city, towards Gihon; for that was to the west of it, ( 2 Chronicles 32:30 ) ,
in the valley, even to the entering in at the fish gate;
through which the fish were brought from Joppa, and where, according to the Targum, they were sold:
and compassed about Ophel;
the eastern part of Mount Zion; some say it was the holy of holies, ( 2 Chronicles 27:3 ) ,
and raised it up a very great height;
built the wall very high there:
and put captains of war in all the fenced cities of Judah;
this he did to put his kingdom in a posture of defence, should it be attacked by the Assyrian army again.
