International Standard Bible Encyclopedia (1915)
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" (2Ch 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 Jos 15:56, etc.
