1 Samuel 26:20-22

20 Now therefore, do not let 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 hunts a partridge in the mountains.

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

22 And David answered and said, Behold the king's spear! Let one of the servants come over and take it.
