1 Samuel 26:3-13

3 Sha'ul pitched camp on Hakhilah Hill, across from Yeshimon, near the road. David was staying in the desert, and he saw that Sha'ul was coming into the desert after him.
4 So David dispatched spies and determined that Sha'ul had definitely come.
5 David set out and went to where Sha'ul had pitched his camp. He saw where Sha'ul and Avner the son of Ner, the commander of his army, were sleeping. Sha'ul was lying inside the barricade with the troops asleep all around him.
6 David said to Achimelekh the Hitti and Avishai the son of Tz'ruyah, Yo'av's brother, "Who will go down with me to Sha'ul in the camp?" Avishai said, "I will go down with you."
7 So David and Avishai went to the soldiers by night. Sha'ul was lying there asleep inside the barricade. His spear was stuck in the ground next to his head, with Avner and the troops asleep all around him.
8 Avishai said to David, "God has handed your enemy over to you today; so now, please, let me pin him to the ground with just one stroke of the spear. I won't strike him a second time."
9 But David said to Avishai, "Don't destroy him! Nobody can raise his hand against ADONAI's anointed without becoming guilty!"
10 David then added, "As ADONAI lives, ADONAI will strike him down, or the day will come for him to die, or he will go down to battle and be swept away.
11 ADONAI forbid that I should raise my hand against ADONAI's anointed! But now, we'll take the spear by his head and the jug of water, and get out of here."
12 So David took the spear and the water jug from Sha'ul's head and got away. Nobody saw or knew about it, and no one awoke, because they were all asleep - a deep sleep from ADONAI had fallen over them.
13 David crossed to the other side and climbed to the top of the distant ridge, leaving a considerable space between them.
