1 Samuel 25:21-22, 33-34

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 returned me evil for good. God do so unto the enemies of David, and more also, if I leave of all that pertain to him by the morning light so much as one man-child.

and blessed be thy discretion, and blessed be thou, that hast kept me this day from bloodguiltiness, and from avenging myself with mine own hand. For in very deed, as Jehovah, the God of Israel, liveth, who hath withholden me from hurting thee, except thou hadst hasted and come to meet me, surely there had not been left unto Nabal by the morning light so much as one man-child.
