The name Euphrates in the Bible
The Euphrates is the single most dominant river of the Bible, even more dominant than the Nile or the Jordan. In the Old Testament this river is called Parat, and as such it is mentioned as early as Genesis 2, where it is one of the four rivers of Eden (the others being Pishon, Gihon, and Haddakel).
The Euphrates even plays a roll in the events surrounding the last days. Four angels that are said to be bound at the Euphrates are to be released under the sixth trumpet (Revelation 9:14). The angel associated with the sixth bowl targets the Euphrates so that it dries up (Revelation 16:12).
