1 Samuel 26:7-12

7So David and Abishai approached the troops by night. Behold, Saul was lying asleep within the barricade with his spear stuck in the ground at his head, and Abner and the troops were sleeping around him.

8Then Abishai said to David, “God has delivered your enemy into your hand today. Now let me pin him to the ground with a single thrust of the spear. I will not have to strike him twice.”

9But David said to Abishai, “Don’t destroy him! For who can lay his hand on Adonai’s anointed and be guiltless?”

10David added, “As Adonai lives, either Adonai will strike him down, or his day will come to die, or he will go down to battle and be swept away.

11Adonai forbid that I should lay my hand on Adonai’s anointed! Now, just take the spear that is at his head and the water jar and let’s go.”

12So David took the spear and the water jar from beside Saul’s head. They got away—and no one saw it, or knew it, or woke up—for all were asleep, for a deep sleep from Adonai had fallen upon them.
