Alush, Mr Rowlands
Alush, Mr. Rowlands (in Fairbairn's Dict. s.v. "Rephidim") regards this as identical with the Wadi el-Eish reported by Dr. Stewart (Tent and Khan, p. 157) as "a large valley coming down from the hills to the east [north] andeventually falling into Wadi Sheikh;" evidently the Wady el-Esh of the Ordnance Map, at the junction of the great wadies Berrar and el-Akhdar, north of Wady el-Sheik, near the eastern termination of Wady Feiran at Wady Solaf.
