A Calebite in the Bible refers to a descendant of Caleb, a brave and godly man from the tribe of Judah who encouraged the Israelites to take possession of Canaan. The term Calebite is only used once to refer to Nabal, a man described as surly, mean, and wicked. As a Calebite, Nabal was descended from Caleb but lacked his courage and faith. Nabal refused a request for provisions from David, almost leading David to destroy him, until Nabal's wife Abigail intervened to save him. Upon hearing of his actions, Nabal's heart failed and he died.
