1. Son of Reuben and founder of the family of the Hezronites (Genesis 46:9; Exodus 6:14; Numbers 26:6). 2. Son of Pharez and grandson of Judah, who was the direct ancestor of David (Genesis 46:12; Ruth 4:18). He had by his first marriage three sons: Jerahmeel; Ram, from whom David descended; and Caleb. Afterward he married the daughter of Machir, who bore him Segub, the father of Jair; and after his death his wife Abijah bore Ashur (1 Chronicles 2:9,21,24). 3. A place marking the southern limit of the territory assigned to Judah, between Kadesh-barnea and Adar (Joshua 15:3). In the parallel list of Numbers 34:4, Hezron and Addar seem to be described as one place, "Hazar-addar."
