Moreover, my father, see, yea, see the skirt of thy robe in my hand: for in that I cut off the skirt of thy robe, and killed thee not, know thou and see that there is neither evil nor transgression in mine hand, and I have not sinned against thee; yet thou huntest my soul to take it. (1 Samuel 24:11)
Saul would probably have paid little attention to the words of David about lifting his hand against the Lord’s anointed, but when he saw the edge of his robe held up before his eyes, and realized how close he had come to death, he trembled before the material evidence of David’s innocence. It was the triumph of spiritual force over physical prowess.
