1 Samuel 26:20-22

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.

22 And David answered and said, Behold the spear, O king! Let then one of the young men come over and fetch it.
