King of Edom — That is, the vice — roy under Jehosaphat, 1 Kings 22:47, here called king: because that word is sometimes used for any prince or chief ruler. Seven days — Because they made a great army, which could move but slowly; and they fetched a greater compass than was usual, for some advantage which they expected by it. No water — A frequent want in those parts; and now, it seems, increased by the extraordinary heat and dryness of the season.
