1 Samuel 26:5-7

5So David set out and went to the place where Saul was camped. David saw the place where Saul and Abner son of Ner, the general in command of his army, were sleeping. Now Saul was lying in the entrenchment, and the army was camped all around him.

6David said to Ahimelech the Hittite and Abishai son of Zeruiah, Joab’s brother, “Who will go down with me to Saul in the camp?” Abishai replied, “I will go down with you.”

7So David and Abishai approached the army at night and found Saul lying asleep in the entrenchment with his spear stuck in the ground by his head. Abner and the army were lying all around him.
