hez'-ron (chetsron, and chetsron; Septuagint Asron):

(1) A son of Reuben (Genesis 46:9 Exodus 6:14), and head of the family of the Hezronites (Numbers 26:6).

(2) A son of Perez, and grandson of Judah (Genesis 46:12 Numbers 26:21 1 Chronicles 2:5, 9, 18, 21, 24, 25; 1 Chronicles 4:1), a direct ancestor of David (Ruth 4:18 f). He appears also in the genealogy of our Lord (Esrom) (Matthew 1:3 Luke 3:33).

HEZRON (2)

(chetsron, "enclosure"): On the South boundary of Judah between "Kadesh-barnea" and "Addar" (Joshua 15:3); in the parallel passage (Numbers 34:4) "Hazar-addar." The two places may have been near together. Conder suggests that the name survives in Jebel Hadhireh, a mountain Northwest of Petra in the Tih.
