From the Sea of Galilee to the Dead Sea is a distance of 65 miles but the Jordan river twists and turns for about 200 miles. The fall is about 590 feet (about 9 feet per mile). Nelson Glueck began his 1945 book, The River Jordan, by describing the river in beautiful terms.
THE JORDAN is a weird stream. It twists and tears its way swiftly downward in an almost incredibly sinuous manner from the sweet waters of the Lake of Galilee to the bitter wastes of the Sea of Salt or Dead Sea. Squirming frantically, burrowing madly, seeking wildly to escape its fate, the Jordan’s course from its crystal-clear beginnings to its literally dark and bitter end is a helpless race to a hopeless goal. Like Lot’s wife, it looks backward, but only inevitably to perish in the perdition of Bahr Lut, the “Sea of Lot,” as the Dead Sea is called by the Arabs. (p. 3)
At the traditional site of the baptism of Jesus by John the Baptist, a place called Qasr el Yahud, a few miles north of the Dead Sea, only very short stretches of the river are visible (Matthew 3:13-17; John 1:28). The photo below shows one of the many curves in the river. Click on the photo for a larger image.
The prophet Jeremiah describes the heavy growth on the banks of the Jordan as the thicket of the Jordan (Jeremiah 12:5; 50:44). Perhaps the reading in the Net Bible, “the thick undergrowth along the Jordan River,” provides a clearer understanding. “Lions could suddenly appear from the bushes” (Jeremiah 49:19; Lalleman, Tyndale Old Testament Commentaries).
