1 Samuel 24:7-11

7And David checked his men with these words, and suffered them not to rise against Saul. And Saul rose up out of the cave, and went on [his] way.

8David also arose afterwards, and went out of the cave, and cried after Saul, saying, My lord the king! And when Saul looked behind him, David bowed with his face to the earth, and did obeisance.

9And David said to Saul, Why dost thou listen to words of men, saying, Behold, David seeks thy hurt?

10Behold, this day thine eyes have seen how that Jehovah had given thee this day into my hand in the cave; and they bade me kill thee; but [mine eye] spared thee; and I said, I will not put forth my hand against my lord, for he is the anointed of Jehovah.

11And see, my father, yes, 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 and see that there is neither evil nor transgression in my hand, and I have not sinned against thee; yet thou liest in wait for my life to take it.
