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.
