1 Samuel 26:16-25

16 This thing is not good that thou hast done. As the LORD liveth, ye are worthy to die, because ye have not kept your master, the LORD's anointed. And now see where the king's spear is, and the cruse of water that was at his bolster.
17 And Saul knew David's voice, and said, Is this thy voice, my son David? And David said, It is my voice, my lord, O king.
18 And he said, Wherefore doth my lord thus pursue after his servant? for what have I done? or what evil is in mine hand?
19 Now therefore, I pray thee, let my lord the king hear the words of his servant. If the LORD have stirred thee up against me, let him accept an offering: but if they be the children of men, cursed be they before the LORD; for they have driven me out this day from abiding in the inheritance of the LORD, saying, Go, serve other gods.
20 Now therefore, let not my blood fall to the earth before the face of the LORD: for the king of Israel is come out to seek a flea, as when one doth hunt a partridge in the mountains.
21 Then said Saul, I have sinned: return, my son David: for I will no more do thee harm, because my soul was precious in thine eyes this day: behold, I have played the fool, and have erred exceedingly.
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.
