Origen of Alexandria : David was besieging Jebus. Jebus was the name of what is now Jerusalem, when it was under the foreigners. So the Jebusites, knowing that David was a lover of the poor, set the blind and the lame up above upon the wall to insult him. But he, when he had taken possession of Jerusalem, was so far from treating badly those who were maimed in body that he even established a law of death for his own soldiers, if anyone should attempt to kill a blind or a lame man. For "everyone who strikes a lame or blind Jebusite," he says, "let him assail him with a dagger" — that is, let him be put to death. For even though they had hated David's life, yet they meet with mercy. Therefore he is deemed worthy of honor from all — those who had insulted David, whom he spared, being the ones of whom it is said, "The lame and the blind shall not enter into the house of the Lord." — FRAGMENTS ON KINGDOMS 15
