1 Samuel 26:19-25

19 Now therefore let my lord the king hear the words of his servant. If it is the LORD who has stirred you up against me, may he accept an offering; but if it is men, may they be cursed before the LORD, for they have driven me out this day that I should have no share in the heritage of the LORD, saying, 'Go, serve other gods.'
20 Now therefore, let not my blood fall to the earth away from the presence of the LORD; for the king of Israel has come out to seek my life, like one who hunts a partridge in the mountains."
21 Then Saul said, "I have done wrong; return, my son David, for I will no more do you harm, because my life was precious in your eyes this day; behold, I have played the fool, and have erred exceedingly."
22 And David made answer, "Here is the spear, O king! Let one of the young men come over and fetch it.
23 The LORD rewards every man for his righteousness and his faithfulness; for the LORD gave you into my hand today, and I would not put forth my hand against the LORD'S anointed.
24 Behold, as your life was precious this day in my sight, so may my life be precious in the sight of the LORD, and may he deliver me out of all tribulation."
25 Then Saul said to David, "Blessed be you, my son David! You will do many things and will succeed in them." So David went his way, and Saul returned to his place.
