ADADAH äd’ ə də (עַדְעָדָֽה, meaning uncertain; festival or bordering suggested). A city of Judah on the southeastern border near Edom (Josh 15:22). The location is unknown. Khirbet ’Ar ’arah c. ten m. SE of Beer-sheba has been suggested. Because the LXX reads ̓Αρουήλ, a possible spelling for ’Ar ’arah, some identify Adadah with Aroer in Judah. From the order of names in Joshua, it would seem that Adadah was located somewhere in the area of Arad and Aroer. Current opinion favors identification with Aroer.
