Ab´igail (father of joy), the wife of a prosperous sheep-master, called Nabal, who dwelt in the district of Carmel, west of the Dead Sea. She is known chiefly for the promptitude and discretion of her conduct in taking measures to avert the wrath of David, which had been violently excited by the insulting treatment which his messengers had received from her husband [NABAL]. She hastily prepared a liberal supply of provisions, of which David's troop stood in much need, and went forth to meet him. Her beauty and prudence made such an impression upon David on this occasion, that when, not long after, he heard of Nabal's death, he sent for her, and she became his wife (1 Samuel 25:14-42). It is usually stated that he had by her two sons, Chileab and Daniel; but it is more likely that the Chileab of 2 Samuel 3:3, is the same as the Daniel of 1 Chronicles 3:1; the son of Abigail being known by both these names.
