Three sites in the Bible—and perhaps foura—are called Aroer (pronounced Ah-roe-air). We call one Aroer of the Negev. The other two—or three—are east of the Jordan River.
Aroer may mean “crest of a mountain.” This very general description would explain why several sites have this name. Or, Aroer may be derived from the name of the juniper plant, Ar’ar (Juniperus Phoenicia), a common plant in arid zones; this meaning also could give rise to several Aroers.
