1 Samuel 25:21-22, 33-34

Now David had said, “Surely in vain I have guarded all that this man has in the wilderness, so that nothing was missed of all that belonged to him; and he has returned me evil for good. May God do so to the enemies of David, and more also, if by morning I leave as much as one male of any who belong to him.”

and blessed be your discernment, and blessed be you, who have kept me this day from bloodshed and from avenging myself by my own hand. Nevertheless, as the LORD God of Israel lives, who has restrained me from harming you, unless you had come quickly to meet me, surely there would not have been left to Nabal until the morning light as much as one male.”
