   The first ten verses of this chapter contain a prediction of
   the taking of Babylon by the Medes and Persians; which is here
   denominated "the desert of the sea," because the country
   around it, and especially towards the sea, was a great morass,
   often overflowed by the Tigris and Euphrates, and only
   rendered habitable by being drained by a number of canals.
