Nabal is a character from the biblical story found in the book of 1 Samuel. He is described as a wealthy but foolish man who owned a large estate in Carmel. Nabal is known for his harshness and lack of hospitality, particularly towards David, who was a fugitive at the time. In the story, David and his men protect Nabal's shepherds and flocks, but when David requests provisions, Nabal refuses and insults him. This leads to a confrontation, but Nabal's wise wife, Abigail, intervenes, preventing violence and ultimately leading to Nabal's downfall.
