Charles Ellicott Commentary Isaiah 10:26

"And Jehovah of hosts will stir up against him a scourge, as in the slaughter of Midian at the rock of Oreb: and his rod will be over the sea, and he will lift it up after the manner of Egypt." — Isaiah 10:26 (ASV)

According to the slaughter of Midian. —The historical associations of Isaiah 9:4 are still in the prophet’s mind. In the history of Judges (Judges 7:25), Oreb and Zeeb are the names both of the Midianite chiefs and of the places where they were slain.

As his rod was upon the sea. —The italics spoil the sense. Better, His rod upon the sea ... He shall lift it up after the manner of Egypt. The ambiguous formula, which had been taken as primarily ominous in Isaiah 10:24, is repeated as a sign of good. There was another rod prominent in that Egyptian history besides that of the oppressor, and that rod had been wielded by the deliverer.
