City of Arad, now Tell Arad
The ancient Canaanite city was about 20 miles south of Hebron. The king of Arad “fought against Israel and took of them prisoners” when they were retreating from Edom (Numbers 21:1; 33:40; Judges 1:16). It was finally subdued by Joshua (12:14).
Arad was later destroyed in by the Romans who built a citadel there in the years following their destruction of Jerusalem.
