("house of rock".) One of Judaea's strongest fortresses in the mountains of Judah, between Halhul and Gedor (Joshua 15:58). Maon, sprung from Hebron, was the father, i.e. founder, of Bethzur. It was fortified by Rehoboam as a stronghold of his new kingdom (2 Chronicles 11:7). The people of Bethzur helped Nehemiah (Nehemiah 3:16) to rebuild the wall of Jerusalem. A district was attached to it, half of which Nehemiah, son of Azbuk, was ruler over. Now Beitsur, commanding the road from Beersheba and Hebron, the main way to Jerusalem from the S. The adjoining spring traditions made the scene of the eunuch's baptism by Philip. The fact of its not being near the road to Gaza makes this doubtful (Acts 8:26; Acts 8:36).
