And it came to pass afterward, that David's heart troubled him, because he had cut off Saul's robe.
All Commentaries on 1 Samuel 24:5 Go To 1 Samuel 24
Gregory of Nyssa
AD 394
This is why the coming together of Saul, who was in pursuit of murder, and of David, who was shunning murder, in the cave is described after many events which it had preceded. The authority to kill was reversed in this event, since the one who was being pursued for execution had authority over the slaughter of his killer, and although he had the right, so far as retribution against his enemy was concerned, he stayed his power so far as consisted with the right and killed his own anger in himself instead of his enemy.
