Euphrates
Hebrew, Perath; Assyrian, Purat; Persian cuneiform, Ufratush,
whence Greek Euphrates, meaning "sweet water." The Assyrian name
means "the stream," or "the great stream." It is generally
called in the Bible simply "the river" (Ex. 23:31), or "the
great river" (Deut. 1:7).
The Euphrates is first mentioned in Gen. 2:14 as one of the
rivers of Paradise. It is next mentioned in connection with the
covenant which God entered into with Abraham (15:18), when he
promised to his descendants the land from the river of Egypt to
the river Euphrates (comp. Deut. 11:24; Josh. 1:4), a covenant
promise afterwards fulfilled in the extended conquests of David
(2 Sam. 8:2-14; 1 Chr. 18:3; 1 Kings 4:24). It was then the
boundary of the kingdom to the north-east. In the ancient
history of Assyria, and Babylon, and Egypt many events are
recorded in which mention is made of the "great river." Just as
the Nile represented in prophecy the power of Egypt, so the
Euphrates represented the Assyrian power (Isa. 8:7; Jer. 2:18).
It is by far the largest and most important of all the rivers
of Western Asia. From its source in the Armenian mountains to
the Persian Gulf, into which it empties itself, it has a course
of about 1,700 miles. It has two sources, (1) the Frat or
Kara-su (i.e., "the black river"), which rises 25 miles
north-east of Erzeroum; and (2) the Muradchai (i.e., "the river
of desire"), which rises near Ararat, on the northern slope of
Ala-tagh. At Kebban Maden, 400 miles from the source of the
former, and 270 from that of the latter, they meet and form the
majestic stream, which is at length joined by the Tigris at
Koornah, after which it is called Shat-el-Arab, which runs in a
deep and broad stream for above 140 miles to the sea. It is
estimated that the alluvium brought down by these rivers
encroaches on the sea at the rate of about one mile in thirty
years.
