David was on the run from Saul. While he was out, he had a group of men with him. They ran a sort of protection racket to protect the local sheep ranchers. One in particular was a wicked-hearted man named Nabal. When David's men were insulted by Nabal, David was ready to slay every male in his household. The attack was only stopped by the quick and decisive actions of Nabal's wife, Abigail.
