118. Verse 14. And the name of the third river is Hiddekel; that is it which goeth eastward toward Asshur; and the fourth river it is Phrath. The “river Hiddekel” is reason, or the clearsightedness of reason. “Asshur” is the rational mind; the “river which goeth eastward toward Asshur” signifies that the clearsightedness of reason comes from the Lord through the internal man into the rational mind, which is of the external man; “Phrath” or Euphrates, is memory-knowledge [scientia], which is the ultimate or boundary.
