1 Samuel 24:8-10

8After that, David got up, went out of the cave, and called out to Saul, “My lord the king!”

When Saul looked behind him, David bowed facedown in reverence 9and said to Saul, “Why do you listen to the words of men who say, ‘Look, David intends to harm you’? 10Behold, this day you have seen with your own eyes that the LORD delivered you into my hand in the cave. I was told to kill you, but I spared you and said, ‘I will not lift my hand against my lord, since he is the LORD’s anointed.’
