Easton's Bible Dictionary Little, a place probably east of the Dead Sea, where Joram discomfited the host of Edom who had revolted from him (2 Kings 8:21). Int. Standard Bible Encyclopedia ZAIR za'-ir (tsa`ir; Zeior): When he invaded Edom, we are told that Joram passed over to Zair and all his chariots with him (2 Kings 8:21). In the parallel passage (2 Chronicles 21:9), "with his captains" (`im sarayw) takes the place of "to Zair" (tsa`irah), probably a copyist's corruption. The place has not been identified. Some have thought that Mt. Seir is intended; others that it means the town of Zoar. Conder suggested ez-Zuweirah, Southeast of the Dead Sea. If Zoar lay in this direction, it is the way by which an invading army might enter Edom.
