8 And David said on that day, Whosoever getteth up to the gutter, and smiteth the Jebusites, and the lame and the blind, that are hated of David's soul, he shall be chief and captain. Wherefore they said, The blind and the lame shall not come into the house.
8 On that day David had said, "Anyone who conquers the Jebusites will have to use the water shaft to reach those 'lame and blind' who are David's enemies.
8 And David said on that day, "Whoever would strike the Jebusites, let him get up the water shaft to attack 'the lame and the blind,' who are hated by David's soul." Therefore it is said, "The blind and the lame shall not come into the house."
8 That day David said, "To get the best of these Jebusites, one must target the water system, not to mention this so-called lame and blind bunch that David hates." (In fact, he was so sick and tired of it, people coined the expression, "No lame and blind allowed in the palace.")
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."
8 On the day of the attack, David said to his troops, "I hate those 'lame' and 'blind' Jebusites. Whoever attacks them should strike by going into the city through the water tunnel. " That is the origin of the saying, "The blind and the lame may not enter the house."
Matthew Henry's Commentary on 2 Samuel 5:8
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!
