A southern bound of Judah (Joshua 15:3). From the Arabic kerak "an even floor," and kaa "a plain." Karkaa is a level expanse, the receptacle of a large body of water. The wady Arish receives on the E. the waters of wady el Kureiyeh and its tributaries. Karkaa was situated perhaps where the northern Kaa or "plain of pools" touches this outlying district of the Holy Land, in the confluence of the wady el Kureiyeh with the Mayein.
