So the king of Israel went, and the king of Judah
 The way of the wilderness of Edom, proposed by the latter: 
 and the king of Edom;
 whom they took with them in their way, who was not properly a king, but a viceroy or deputy, see ( 1 Kings 22:47 ) 
 and they fetched a compass of seven days journey;
 they went round the Dead Sea, and through the wilderness of Edom, and so to the borders of Moab: 
 and there was no water for the host, and for the cattle that followed
 them;
 neither for the soldiers in the army, nor the cattle that drew the carriages, being in a wilderness.
