6 David and his men immediately set out for Jerusalem to take on the Jebusites, who lived in that country. But they said, "You might as well go home! Even the blind and the lame could keep you out. You can't get in here!" They had convinced themselves that David couldn't break through.
Matthew Henry's Commentary on 2 Samuel 5:6
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!
