2 Kings 3:9

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.
