1 Samuel 26:22-25 (KJV)
22 And David answered and said, Behold the king’s spear! and let one of the young men come over and fetch it.
23 The Lord render to every man his righteousness and his faithfulness; for the Lord delivered thee into my hand to day, but I would not stretch forth mine hand against the Lord’s anointed.
24 And, behold, as thy life was much set by this day in mine eyes, so let my life be much set by in the eyes of the Lord, and let him deliver me out of all tribulation.
25 Then Saul said to David, Blessed be thou, my son David: thou shalt both do great things, and also shalt still prevail. So David went on his way, and Saul returned to his place.
