1 Samuel 24:7-11

7So 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 afterward, 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, Wherefore hearkenest thou to men’s words, saying, Behold, David seeketh thy hurt?

10Behold, this day thine eyes have seen how that the LORD had delivered thee today into mine hand in the cave: and some bade me kill thee: but mine eye spared thee; and I said, I will not put forth mine hand against my lord; for he is the LORD’S anointed.

11Moreover, 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, though thou huntest after my soul to take it.
