1 Samuel 24:3-11
And he came to the sheepcotes by the way, where was a cave; and Saul went in to cover his feet: and David and his men remained in the sides of the cave. And the men of David said unto him, Behold the day of which the LORD said unto thee, Behold, I will deliver thine enemy into thine hand, that thou mayest do to him as it shall seem good unto thee. Then David arose, and cut off the skirt of Saul's robe privily. And it came to pass afterward, that David's heart smote him, because he had cut off Saul's skirt. And he said unto his men, The LORD forbid that I should do this thing unto my master, the LORD'S anointed, to stretch forth mine hand against him, seeing he is the anointed of the LORD. read more
So David stayed his servants with these words, and suffered them not to rise against Saul. But Saul rose up out of the cave, and went on his way. David 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 stooped with his face to the earth, and bowed himself. And David said to Saul, Wherefore hearest thou men's words, saying, Behold, David seeketh thy hurt? Behold, this day thine eyes have seen how that the LORD had delivered thee to day 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. 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. show less
