1 Samuel 26:7-14, 21-25

So David and Abishai went right into Saul’s camp and found him asleep, with his spear stuck in the ground beside his head. Abner and the soldiers were lying asleep around him. “God has surely handed your enemy over to you this time!” Abishai whispered to David. “Let me pin him to the ground with one thrust of the spear; I won’t need to strike twice!” “No!” David said. “Don’t kill him. For who can remain innocent after attacking the LORD’s anointed one? Surely the LORD will strike Saul down someday, or he will die of old age or in battle. The LORD forbid that I should kill the one he has anointed! But take his spear and that jug of water beside his head, and then let’s get out of here!” So David took the spear and jug of water that were near Saul’s head. Then he and Abishai got away without anyone seeing them or even waking up, because the LORD had put Saul’s men into a deep sleep. David climbed the hill opposite the camp until he was at a safe distance. Then he shouted down to the soldiers and to Abner son of Ner, “Wake up, Abner!” “Who is it?” Abner demanded.

Then Saul confessed, “I have sinned. Come back home, my son, and I will no longer try to harm you, for you valued my life today. I have been a fool and very, very wrong.” “Here is your spear, O king,” David replied. “Let one of your young men come over and get it. The LORD gives his own reward for doing good and for being loyal, and I refused to kill you even when the LORD placed you in my power, for you are the LORD’s anointed one. Now may the LORD value my life, even as I have valued yours today. May he rescue me from all my troubles.” And Saul said to David, “Blessings on you, my son David. You will do many heroic deeds, and you will surely succeed.” Then David went away, and Saul returned home.
