And David dwelt in the strong hold, and called it the city of David. And David built round about from Millo and inward.

So David dwelled in the fort, and called it the city of David. And David built round about from Millo and inward.

So David took the strong tower for his living-place, naming it the town of David. And David took in hand the building of the town all round, starting from the Millo.

Then David lived in the stronghold, and he called it: the City of David. And he built it up on all sides, from Millo and inward.

David dwelt in the fort - or stronghold, (as in 2-Samuel 5:7) i. e. eventually, when the buildings were completed, which may not have been for two or three years. Millo appears to have been a fortress of some kind, the northern defense of the city of David, and to have been a part of the original Canaanite defenses of Zion, as appears probable also from there having been a fortress called the house of Millo in the Canaanite city of Shechem. (Judges 9:6 note, and 2-Samuel 9:1-13 :20.) Millo may be the native name. Some identify it with the great platform called the Haram es Sherif.
David built round about - Probably meaning built his own house and other houses and streets, all, in short, that caused it to be coiled the city of David. (Compare 1-Chronicles 11:8.) The buildings were within, on the south of Millo, so as to be protected by it on the north, as they were east, west. and south, by the precipitous ravines.

So David dwelt in the fort, and called it the city of David. And David built round about from (e) Millo and inward.
(e) He built from the town house round about to his own house (1-Chronicles 11:8).

So David dwelt in the fort,.... The strong hold of Zion, which he took:
and called it the city of David; from his own name, to keep up the memory of his taking it, and of his habitation in it:
and David built round about, from Millo and inward; built a wall about it, and enlarged the place, increased the buildings both within and without. Millo is supposed to be a ditch round the fort, full of water, from whence it had its name; or was a large hollow place which divided the fort from the lower city, and which afterwards Solomon filled up, and made it a level, and therefore is called so here by anticipation; though Jarchi says it was done by David. According to Dr. Lightfoot (o), it was a part or Sion, or some hillock, east up against it on the west side; his first sense is best, Millo being no other than the fortress or citadel; which, as Josephus says (p), David joined to the lower city, and made them one body, and erecting walls about it made Joab superintendent of them; and this was the "round about", or circuit, which David made, reaching from Millo, or the citadel, to that again, which is meant by "inward", or "to the house" (q), as it should be rendered; that is, to the house of Millo, as in 2-Kings 12:20; and so it is said 1-Chronicles 11:8; that David built the city "from Millo round about"; that is, to the same place from whence he began (r).

David dwelt in the fort, &c.--Having taken it by storm, he changed its name to "the city of David," to signify the importance of the conquest, and to perpetuate the memory of the event.
David built round about from Millo and inward--probably a row of stone bastions placed on the northern side of Mount Zion, and built by David to secure himself on that side from the Jebusites, who still lived in the lower part of the city. The house of Millo was perhaps the principal corner tower of that fortified wall.

"David dwelt in the fort," i.e., he selected the fort or citadel as his palace, "and called it David's city." David may have been induced to select the citadel of Zion as his palace, and by so doing to make Jerusalem the capital of the whole kingdom, partly by the natural strength of Zion, and partly by the situation of Jerusalem, viz., on the border of the tribes of Benjamin and Judah, and tolerably near to the centre of the land. "And David built, i.e., fortified (the city of Zion), round about from Millo and inwards." In the Chronicles we have ועד־הסּביב, "and to the environs or surroundings," i.e., to the encircling wall which was opposite to the Millo. The fortification "inwards" must have consisted in the enclosure of Mount Zion with a strong wall upon the north side, where Jerusalem joined it as a lower town, so as to defend the palace against the hostile attacks on the north or town side, which had hitherto been left without fortifications. The "Millo" was at any rate some kind of fortification, probably a large tower or castle at one particular part of the surrounding wall (comp. Judges 9:6 with Judges 9:46 and Judges 9:49, where Millo is used interchangeably with Migdal). The name ("the filling") probably originated in the fact that through this tower or castle the fortification of the city, or the surrounding wall, was filled or completed. The definite article before Millo indicates that it was a well-known fortress, probably one that had been erected by the Jebusites. With regard to the situation of Millo, we may infer from this passage, and 1-Chronicles 11:8, that the tower in question stood at one corner of the wall, either on the north-east or north-west, "where the hill of Zion has the least elevation and therefore needed the greatest strengthening from without" (Thenius on 1-Kings 9:15). This is fully sustained both by 1-Kings 11:27, where Solomon is said to have closed the breach of the city of David by building (fortifying) Millo, and by 2-Chronicles 32:5, where Hezekiah is said to have built up all the wall of Jerusalem, and made Millo strong, i.e., to have fortified it still further (vid., 1-Kings 9:15 and 1-Kings 9:24).
