1 Samuel 25:20-22

It came about as she was riding on her donkey and coming down by the hidden part of the mountain, that behold, David and his men were coming down toward her; so she met them. 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.”
