The Euphrates River is about 1,800 miles long, one thousand feet to one mile at some points wide, and is on the average 57 feet deep, For a long time, this river was a formidable barrier to East-West communication and transportation. Although modern transportation systems can cross the river easily, the water has nevertheless become a subtle dividing line.

The drying of the Euphrates as prophesied in Revelation will serve as a sign to the kings of the east to begin a catastrophic invasion.
