1 Samuel 24:10

10 Lo, this day your eyes have seen how the LORD gave you today into my hand in the cave; and some bade me kill you, but I spared you. I said, 'I will not put forth my hand against my lord; for he is the LORD'S anointed.'

1 Samuel 24:10 In-Context

8 Afterward David also arose, and went out of the cave, and called after Saul, "My lord the king!" And when Saul looked behind him, David bowed with his face to the earth, and did obeisance.
9 And David said to Saul, "Why do you listen to the words of men who say, 'Behold, David seeks your hurt'?
10 Lo, this day your eyes have seen how the LORD gave you today into my hand in the cave; and some bade me kill you, but I spared you. I said, 'I will not put forth my hand against my lord; for he is the LORD'S anointed.'
11 See, my father, see the skirt of your robe in my hand; for by the fact that I cut off the skirt of your robe, and did not kill you, you may know and see that there is no wrong or treason in my hands. I have not sinned against you, though you hunt my life to take it.
12 May the LORD judge between me and you, may the LORD avenge me upon you; but my hand shall not be against you.
