1 Samuel 25:14-16

14One of the servants told Abigail, Nabal’s wife, “David sent messengers from the wilderness to give our master his greetings, but he hurled insults at them. 15Yet these men were very good to us. They did not mistreat us, and the whole time we were out in the fields near them nothing was missing. 16Night and day they were a wall around us the whole time we were herding our sheep near them.
