Verse 7. -
The stronghold of Zion: the same is the city of David. Zion was the hill on the southwestern side of the city; but we learn from ver. 9 that the Jebusites had not occupied the whole of it, but a part only, which was their
stronghold, round which there would be scattered dwellings, as the whole tribe dwelt there. The total area of the hill top was about sixty acres, and it was now quickly covered with houses, and called "the city of David," after its captor. The view of Dr. Birch and others, that the stronghold of Zion was Ophel, is rendered untenable by the fact that this southern tongue of Mount Moriah is completely commanded by other parts of the hill. According to Gesenius, Zion means "sunny;" others render it "the dry hill;" others, "lofty;" and Furst, "the castle." None of these derivations is of any real value, as the word is probably Hittite.
5:6-10 The enemies of God's people are often very confident of their own strength, and most secure when their day to fall draws nigh. But the pride and insolence of the Jebusites animated David, and the Lord God of hosts was with him. Thus in the day of God's power, Satan's strong-hold, the human heart, is changed into a habitation of God through the Spirit, and into a throne on which the Son of David rules, and brings every thought into obedience to himself. May He thus come, and claim, and cleanse, each of our hearts; and, destroying every idol, may he reign there for ever!
Nevertheless, David took the strong hold of Zion,.... A fortress without the city, and separate from it, and which was very strong; and the taking it might facilitate the taking of the city, which yet as appears by what follows, was very difficult to do:
the same is the city of David; it was afterwards so called, where he built an house, and dwelt.
