Founded by God, a "desert" on the ascent from the valley of the Dead Sea towards Jerusalem. It lay beyond the wilderness of Tekoa, in the direction of Engedi (2 Chronicles 20:16, 20). It corresponds with the tract of country now called el-Hasasah.

je-roo'-el, jer'-oo-el (yeru'el, "founded by El"): Jahaziel prophesied that King Jehoshaphat should meet the hordes of Moabites and Ammonites, after they had come up by the "ascent of Ziz," "at the end of the valley (i.e. wady), before the wilderness of Jeruel" (2 Chronicles 20:16). The particular part of the wilderness intended, is unknown. Cheyne (Encyclopedia Biblica) thinks this may be an error for the Jezreel of Judah, mentioned in Joshua 15:56, etc.
