Euphrates
Name meaning: "that makes fruitful"
The Euphrates (Hebrew Perath) is the greatest river of western Asia, rising in the mountains of Armenia and flowing some 1,700 miles southeast through Syria and the Mesopotamian plain to join the Tigris and empty into the Persian Gulf. Together the two rivers define Mesopotamia, "the land between the rivers," cradle of the earliest civilizations. So dominant was it in the world of the Bible that it is often called simply "the River" or "the great river" (Genesis 31:21; Joshua 24:2).
The Euphrates appears at the very beginning and end of Scripture. It is named as the fourth of the rivers flowing out of Eden (Genesis 2:14), and it marks the ideal northeastern boundary of the land God promised to Abraham — "from the river of Egypt to the great river, the river Euphrates" (Genesis 15:18; Deuteronomy 11:24; Joshua 1:4). That ideal was briefly realized when David extended his dominion to the river and Solomon reigned "over all the kingdoms from the Euphrates to the land of the Philistines" (2 Samuel 8:3; 1 Kings 4:21).
Yet the Euphrates was also the highway of the great empires that overwhelmed Israel. Abraham himself had come from beyond the River, from Ur and Haran (Joshua 24:2–3); and across it Assyria and Babylon swept to carry the northern and southern kingdoms into exile. On its banks at Carchemish, Nebuchadnezzar shattered the army of Pharaoh Neco in 605 BC, sealing Babylon's mastery of the age (Jeremiah 46:2). By the canals of the Euphrates the captives of Judah sat down and wept, remembering Zion (Psalm 137:1), and there Jeremiah enacted his sign of the ruined loincloth and sank his scroll of doom against Babylon beneath the river's waters (Jeremiah 13:4–7; Jeremiah 51:63).
In the visions of Revelation the Euphrates returns as a boundary of judgment at the end of the age: four angels are loosed from "the great river Euphrates" to bring forth their host (Revelation 9:14), and under the sixth bowl the river is dried up "to prepare the way for the kings from the east" (Revelation 16:12). Thus from the fruitful river of Eden to the frontier of the promised land, from the road of exile to the last gathering of the nations, the Euphrates threads the whole biblical story — at once a sign of the breadth of God's promise and of the empires through which he worked his purposes of judgment and salvation.
