Now after this he built a wall without the city of David, on the west side of Gihon, in the valley, even to the entering in at the fish gate, and compassed about Ophel, and raised it up a very great height, and put captains of war in all the fenced cities of Judah.

Now after this he built an outer wall to the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish gate; and he compassed Ophel about with it , and raised it up to a very great height: and he put valiant captains in all the fortified cities of Judah.

After this he built a wall without the city of David, on the west side of Gihon in the valley, from the entering in of the fish gate round about to Ophel, and raised it up to a great height: and he appointed captains of the army in all the fenced cities of Juda:

And after this he built the outer wall of the city of David, on the west, toward Gihon, in the valley, even to the entrance of the fish-gate, and carried it round Ophel, and raised it up a very great height; and he put captains of war in all the fortified cities of Judah.

Now after this, he built a wall without the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish-gate, and compassed about Ophel, and raised it up a very great highth, and put captains of war in all the fortified cities of Judah.

And after this he hath built an outer wall to the city of David, on the west of Gihon, in the valley, and at the entering in at the fish-gate, and it hath gone round to the tower, and he maketh it exceeding high, and he putteth heads of the force in all the cities of the bulwarks in Judah.

After this he made an outer wall for the town of David, on the west side of Gihon in the valley, as far as the way into the town by the fish doorway; and he put a very high wall round the Ophel; and he put captains of the army in all the walled towns of Judah.

Now after this he built an outer wall to the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish gate; and he compassed about Ophel, and raised it up a very great height; and he put captains of the army in all the fortified cities of Judah.

After these things, he built a wall outside the City of David, to the west of Gihon, at the steep valley, from the entrance to the fish gate, circling around as far as Ophel. And he raised it up greatly. And he appointed leaders of the army in all the fortified cities of Judah.

Rather, "he built the outer wall of the city of David on the west of Gihon-in-the-valley." The wall intended seems to have been that toward the northeast, which ran from the vicinity of the modern Damascus gate across the valley of Gihon, to the "fish-gate" at the northeast corner of the "city of David."
We may gather from this verse that, late in his reign, Manasseh revolted from the Assyrians, and made preparations to resist them if they should attack him. Assyria began to decline in power about 647 B.C., and from that time her outlying provinces would naturally begin to fall off. Manasseh reigned until 642 B.C.

He built a wall - This was probably a weak place that he fortified; or a part of the wall which the Assyrians had broken down, which he now rebuilt.

Now after this he built a wall without the city of David, on the west side of (e) Gihon, in the valley, even to the entering in at the fish gate, and compassed about (f) Ophel, and raised it up a very great height, and put captains of war in all the fenced cities of Judah.

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 (l) thinks this is the wall of the pool of Siloah, Nehemiah 3:15 which seems to be the first and oldest wall, as Josephus (m); for that turning to the north bent towards the pool of Siloam; an Arabic writer (n) 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.

he built a wall without the city . . . on the west side of Gihon . . . even to the entering in at the fish gate--"The well-ascertained position of the fish gate, shows that the valley of Gihon could be no other than that leading northwest of Damascus gate, and gently descending southward, uniting with the Tyropœon at the northeast corner of Mount Zion, where the latter turns at right angles and runs towards Siloam. The wall thus built by Manasseh on the west side of the valley of Gihon, would extend from the vicinity of the northeast corner of the wall of Zion in a northerly direction, until it crossed over the valley to form a junction with the outer wall at the trench of Antonia, precisely in the quarter where the temple would be most easily assailed" [BARCLAY].

After his return, Manasseh took measures to secure his kingdom, and especially the capital, against hostile attacks. "He built an outer wall of the city of David westward towards Gihon in the valley, and in the direction of the fish-gate; and he surrounded the Ophel, and made it very high." The words היצונה חומה (without the article) point to the building of a new wall. But since it has been already recorded of Hezekiah, in 2-Chronicles 32:5, that he built "the other wall without," all modern expositors, even Arnold in Herz.'s Realenc. xviii. S. 634, assume the identity of the two walls, and understand ויּבן of the completion and heightening of that "other wall" of which it is said מאד ויּגבּיהה, and which shut in Zion from the lower city to the north. In that case, of course, we must make the correction החומה. The words "westward towards Gihon in the valley, and לבוא ב, in the direction to (towards) the fish-gate," are then to be taken as describing the course of this wall from its centre, first towards the west, and then towards the east. For the valley of Gihon lay, in all probability, outside of the western city gate, which occupied the place of the present Jaffa gate. But the fish-gate was, according to Nehemiah 3:3, at the east end of this wall, at no great distance from the tower on the north-east corner. The valley (הנּהל) is a hollow between the upper city (Zion) and the lower (Acra), probably the beginning of the valley, which at its south-eastern opening, between Zion and Moriah, is called Tyropoion in Josephus. The words, "he surrounded the Ophel," sc. with a wall, are not to be connected with the preceding clauses, as Berth. connects them, translating, "he carried the wall from the north-east corner farther to the south, and then round the Ophel;" for "between the north-east corner and the Ophel wall lay the whole east wall of the city, as far as to the south-east corner of the temple area, which yet cannot be regarded as a continuation of the wall to the Ophel wall" (Arnold, loc. cit.). Jotham had already built a great deal at the Ophel wall (2-Chronicles 27:3). Manasseh must therefore only have strengthened it, and increased its height. On the words שׂ ויּשׂם cf. 2-Chronicles 32:6 and 2-Chronicles 17:2.
