1 Samuel 25:20-22

And it was so, as she rode on the ass, that she came down by the covert of the hill, and, behold, David and his men came down against her; and she met them. Now David had said, Surely in vain have I kept all that this fellow hath in the wilderness, so that nothing was missed of all that pertained unto him: and he hath requited me evil for good. So and more also do God unto the enemies of David, if I leave of all that pertain to him by the morning light any that pisseth against the wall.
