Bethzur: house of rock, a town in the mountains of Judah (Joshua 15:58), about 4 miles to the north of Hebron. It was built by Rehoboam for the defence of his kingdom (2 Chronicles 11:7). It stood near the modern ed-Dirweh. Its ruins are still seen on a hill which bears the name of Beit-Sur, and which commands the road from Beer-sheba and Hebron to Jerusalem from the south.
