1 Samuel 26:5-7

5David then set out and came to the place where Saul had camped. And David saw the place where Saul lay, and 1Abner the son of Ner, the commander of his army; and Saul was lying in the circle of the camp, and the people were camped around him.

6Then David said to Ahimelech 2the Hittite and to 3Abishai the son of Zeruiah, Joab’s brother, saying, “Who 4will go down with me to Saul in the camp?” And Abishai said, “I will go down with you.” 7So David and Abishai came to the people by night, and behold, Saul lay sleeping inside the circle of the camp with his spear stuck in the ground at his head; and Abner and the people were lying around him.
