That says to the deep, Be dry, and I will dry up your rivers:
All Commentaries on Isaiah 44:27 Go To Isaiah 44
Ephrem The Syrian
AD 373
“I will dry up your rivers,” that is, he will extend his hand over the Euphrates. In a different way, we may intend that the Lord will destroy the devil and his frauds, into which he plunges people as into a sea. And the rivers, which he dries up, are the armies of his iniquity.
