1 Samuel 26:19-21

19 Now therefore, I pray thee, let my lord the king hear the words of his servant. If it be LORD who has stirred thee up against me, let him accept an offering, but if it be the sons of men, cursed be they before LORD. For they have driven me out this day that I should not cling to the inheritance of LORD, saying, Go, serve other gods.

20 Now therefore, let not my blood fall to the earth away from the presence of LORD. For the king of Israel has come out to seek a flea, as when a man hunts a partridge in the mountains.

21 Then Saul said, I have sinned. Return, my son David, for I will no more do thee harm because my life was precious in thine eyes this day. Behold, I have played the fool, and have erred exceedingly.
