The Lord shall utterly destroy the tongue of the Egyptian sea.
The Egyptian sea and the river
The “tongue,” i.e., the bay (cf. Jos_15:2)
of the Red Sea (the Gulf of Suez) will be “banned,” i.e., rendered harmless to those who would cross it, by being dried up; “the river” (the Euphrates), swift and too deep to be forded as it is, will be split into seven separate channels, which separately may be forded without danger. (Prof. Driver, D. D.)
