6 And the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land, who spoke to David, saying, "You shall not come in here; but the blind and the lame will repel you," thinking, "David cannot come in here." 7 Nevertheless David took the stronghold of Zion (that is, the City of David). 8 Now David said on that day, "Whoever climbs up by way of the water shaft and defeats the Jebusites (the lame and the blind, who are hated by David's soul), he shall be chief and captain." Therefore they say, "The blind and the lame shall not come into the house." 9 Then David dwelt in the stronghold, and called it the City of David. And David built all around from the Millo and inward.
Matthew Henry's Commentary on 2 Samuel 5:6-9
Commentary on 2 Samuel 5:6-10
(Read 2 Samuel 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!
