Isaiah 19:5

The waters — Which may be understood either, Metaphorically, of the taking away of their dominion or commerce, &c. or rather, Properly, as may be gathered from the following words. For as the river Nile, when it had a full stream, and free course, did pour forth a vast quantity of waters by its seven famous mouths into the sea, so when that was dried up, which is expressed in the next clause, those waters did truly and properly fail from the sea. So there is no need of understanding by sea either the river Nile, or the great lake of Maeris, which, after the manner of the Hebrews, might be so called. The river — Nile: upon whose fulness and overflow both the safety and the wealth of the land depended; and therefore this was a very terrible judgment. Dried up — Not totally, but in a very great measure.
