Son of Ephah.Grandson of Ephah, Caleb’s concubine (1Chr.2.46).
GAZEZ gā’ zĭz (Heb. גָּזֵֽז, prob. derived from the word for shearing sheep, גָּזַז, H1605). The word occurs as the name of a Calebite family only in 1 Chronicles 2:46 twice. It means something like “born at shearing time.” They were a son and a brother of Haran; the older commentators thought them to be a son and grandson of Caleb.
