1 Samuel 26:15

So David took the spear and the jar of water from Saul’s head, and they went away. No man saw it, or knew it, nor did any awake; for they were all asleep, because a deep sleep from the LORD had fallen on them.

Then David went over to the other side, and stood on the top of the mountain far away, a great space being between them;

and David cried to the people, and to Abner the son of Ner, saying, “Don’t you answer, Abner?”

Then Abner answered, “Who are you who calls to the king?”

This thing isn’t good that you have done. As the LORD lives, you are worthy to die, because you have not kept watch over your lord, the LORD’s anointed. Now see where the king’s spear is, and the jar of water that was at his head.”

Saul recognized David’s voice, and said, “Is this your voice, my son David?”

David said, “It is my voice, my lord, O king.”

He said, “Why does my lord pursue his servant? For what have I done? What evil is in my hand?
