1 Samuel 26:1-8

Now some men from Ziph came to Saul at Gibeah to tell him, “David is hiding on the hill of Hakilah, which overlooks Jeshimon.” So Saul took 3,000 of Israel’s elite troops and went to hunt him down in the wilderness of Ziph. Saul camped along the road beside the hill of Hakilah, near Jeshimon, where David was hiding. When David learned that Saul had come after him into the wilderness, he sent out spies to verify the report of Saul’s arrival. David slipped over to Saul’s camp one night to look around. Saul and Abner son of Ner, the commander of his army, were sleeping inside a ring formed by the slumbering warriors. “Who will volunteer to go in there with me?” David asked Ahimelech the Hittite and Abishai son of Zeruiah, Joab’s brother. “I’ll go with you,” Abishai replied. 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!”
