Afterward he brought me again unto the door of the house; and, behold, waters issued out from under the threshold of the house eastward: for the forefront of the house stood toward the east, and the waters came down from under from the right side of the house, at the south side of the altar. Ezekiel 47:1
Some problems are created by certain enigmatic aspects in Ezekiel. Chapter 47 relates in detail that one day water will come out "from under the threshold of the temple towards the east" and will rise until it is "deep enough to swim in", causing "a great number of trees" to grow on each of its banks. The Dead Sea, at that appointed time only about two kilometers from Jerusalem at its nearest point, will be full of "fish of many kinds–like the fish of the Great Sea [the Mediterranean]."
This, according to scientists, is possible at any time, if the so-called "East African Rift", which begins in far-off Tanzania and comes up through the Red Sea to the Dead Sea depression, were for some reason to split. I have myself seen detailed maps which show how the situation is being followed by seismographic and other methods. There are channels in the Red Sea basin in which the water temperature is as high as 50 degrees centigrade because of the thinness of the earth’s crust, and the shores of the Aqaba bay, for example, are continually moving away from each other at a significant rate. Joel 3:18 and Zechariah 14:4-8 offer similar descriptions of mystical water-miracles in the Last Days. Geological research shows this all to be quite possible.
