isaiah 19:7 The paper reeds by the brooks, by the mouth of the brooks, and every thing sown by the brooks, shall wither, be driven away, and be no more. - Free Bible Online

      7. paper-reeds--rather, pastures, literally, "places naked" of wood, and famed for rich herbage, on the banks of the Nile [GESENIUS]. Compare Ge 13:10; De 11:10. HORSLEY translates, "nakedness upon the river," descriptive of the appearance of a river when its bottom is bare and its banks stripped of verdure by long drought: so Vulgate.
      the brooks--the river.
      mouth--rather, "the source" [Vulgate]. "Even close to the river's side vegetation shall be so withered as to be scattered in the shape of powder by the wind" (English Version, "driven away") [HORSLEY].
