Jamieson, Fausset & Brown, on Isa 11:15
“And the Lord shall lay waste the tongue of the sea of Egypt, and shall lift up his hand over the river in the strength of his spirit: and he shall strike it in the seven streams, so that men may pass through it in their shoes.”
There shall be a second exodus, destined to eclipse even the former one from Egypt in its wonders. So the prophecies elsewhere (Psa 68:22; Exo 14:22; Zac 10:11). The same deliverance furnishes the imagery by which the return from Babylon is described (Isa 48:20-21). destroy--literally, "devote," or "doom," that is, dry up; for what God dooms, perishes (Psa 106:9 Nah 1:4). tongue--the Bubastic branch of the Nile [VITRINGA]; but as the Nile was not the obstruction to the exodus, it is rather the west tongue or Heroöpolite fork of the Red Sea. with . . . mighty wind--such as the "strong east wind" (Exo 14:21), by which God made a way for Israel through the Red Sea. The Hebrew for "mighty" means terrible. MAURER translates, "With the terror of His anger"; that is, His terrible anger. in the seven streams--rather, "shall smite it (divide it by smiting) into seven (many) streams, so as to be easily crossed" [LOWTH]. So Cyrus divided the river Gyndes, which retarded his march against Babylon, into three hundred sixty streams, so that even a woman could cross it [HERODOTUS, 1.189]. "The river" is the Euphrates, the obstruction to Israel's return "from Assyria" (Isa 11:16), a type of all future impediments to the restoration of the Jews. dry shod--Hebrew, "in shoes." Even in sandals they should be able to pass over the once mighty river without being wet (Rev 16:12).
