But there the glorious LORD will be unto us a place of broad rivers and streams; in which shall go no galley with oars, neither shall majestic ships pass by.
Read Chapter 33
George Leo Haydock
Of rivers. He speaks of the rivers of endless joys that flow from the throne of God to water the heavenly Jerusalem, where no enemy's ship can come (Challoner)

For the plainly spoken words of these interpretations have made the views of the ancient fathers clear to us. If we view the words of the text according to the plain meaning of the words and not according to the obscured meaning of allegory, then we will see that Isaiah exclaimed (as interpreted by the holy church), “The place of rivers, the broadest and open streams.” For the sayings of the Old Testament were as narrow and close streams, which brought together the various views in their culture. But the teachings of the holy church are broad and open streams, because its declarations are at once many in number to those who find them and are plain to those who seek them. - "Morals on the Book of Job 4.18.60"
