So David and Abishai went to the army by night; there Saul lay sleeping within the encampment, with his spear stuck in the ground at his head; and Abner and the army lay around him.
David rose early in the morning, left the sheep with a keeper, took the provisions, and went as Jesse had commanded him. He came to the encampment as the army was going forth to the battle line, shouting the war cry.
Then David said to Ahimelech the Hittite, and to Joab's brother Abishai son of Zeruiah, “Who will go down with me into the camp to Saul?” Abishai said, “I will go down with you.”
Abishai said to David, “God has given your enemy into your hand today; now therefore let me pin him to the ground with one stroke of the spear; I will not strike him twice.”
