1 Samuel 24:8-10

8After that, David got up, went out of the cave, and called to Saul, “My lord the king!” When Saul looked behind him, David knelt low with his face to the ground and paid homage.

9David said to Saul, “Why do you listen to the words of people who say, ‘Look, David intends to harm you’?

10You can see with your own eyes that the Lord handed you over to me today in the cave. Someone advised me to kill you, but I took pity on you and said: I won’t lift my hand against my lord, since he is the Lord’s anointed.
