ZERED (zē'rĕd, Heb. zeredh). A valley running northwestward on the border between Moab and Edom and ending at the southern end of the Dead Sea; also the brook that follows the valley. A camping place of Israel at the end of their long wanderings (
Because Israel penetrated the wilderness E of Moab before crossing the Zered, some identify it with the Wadi Kerak or some tributary of the Kerak or the Arnon—the Ferranj or Seil Sa ’ideh perhaps. Others, postulating a journey eastward up the valley before the crossing, accept identification (here favored) with Wadi el-Hesa.
Like the Kerak and Arnon, the Hesa flows intermittently in a shallow valley across the plateau, but replenished by rainfall, tributaries and esp. springs, flows perennially to its terminal oasis through a canyon cleaving the fault-weakened escarpment. Steep-walled but broad-floored and flanked with cultivable terraces, this wadi formed both the historic divide between Edom and Moab and a difficult but practicable route to the plateau.
