2 Kings 3:9
So the king of Israel went, and the king of Judah, and the king of Edom: and they fetched a compass of seven days' journey: and there was no water for the host, and for the cattle that followed them.
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.
