Matthew Poole and continuators on Isaiah 33:21

21. But there the glorious LORD will be unto us a place of broad rivers and streams , wherein shall go no galley with oars, neither shall gallant ships pass thereby .

In and about Zion.

Though we have nothing but a small and contemptible Brook to defend us; yet God will be as sure and strong a Defence to us, as if we were surrounded with such great Rivers, as Nilus or Euphrates, which were a great security to Egypt and Babylon.

But although they shall have from God, the security of a great River, yet they shall be freed from the disadvantage of it; which is, That the Enemies may come against them in Ships; for no Galleys, nor Ships of the Enemies shall be able to come into this River to annoy them.

Marginal references: Or, but there (glorious is the LORD) we shall have a place, &c.; Heb. broad of spaces or hands.
