1 Samuel 26:21, 24

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.

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.
