(anc. geog.), a city lying to the south of Judah and the land of Canaan, in Arabia Petraea. The Israelites having advanced towards the land of Canaan (Numb. xxi. 1.), the king of Arad opposed their passage, defeated them, and took a great booty from them; but they destroyed his country as soon as they became became masters of the land of Canaan (Num. xxxiii.) Arad was rebuilt, and Eusebius places it in the neighbourhood of Khades, at the distance of 20 miles from Hebron. The Israelites, in their passage through the wilderness, having departed from Sepher, came to Arad, and from thence to Makkelath.
