And the name of the third river is Tigris: the same passeth along by the Assyrians. And the fourth river is Euphrates.

“The Church, setting forth the likeness of paradise, includes within her walls fruit-bearing trees, whereof that which does not bring forth good fruit is cut off and is cast into the fire. These trees she waters with four rivers, that is, with the four Gospels, wherewith, by a celestial inundation, she bestows the grace of saving baptism. Can any one water from the Church's fountains who is not within the Church? Can one impart those wholesome and saving draughts of paradise to any one if he is perverted, and of himself condemned, and banished outside the fountains of paradise, and has dried up and failed with the dryness of an eternal thirst?”

“Perhaps, however, those people who like to talk from their own wisdom do not concede again that these rivers are rivers or these waters really waters but propound some different interpretation to people ready to lend them their ears. Let us, however, I beg you, not be convinced by them but block our ears against them; let us instead place our credence in sacred Scripture and heed what is told us there.”

“Then there is the ocean that encircles the entire earth like a sort of river and to which it seems to me that Scripture referred when it said that "a river flowed out of paradise." It has sweet potable water and supplies the seas, but because the water remains stagnant in the seas for a long time it becomes brackish. The sun and the waterspouts are constantly drawing up the less dense water, and from this the clouds are formed and the rain comes, the water becoming sweet by filtration. This ocean is divided into four heads, of four rivers. The name of the first is Pishon; this is the Ganges of India. The name of the second is Gehon; this is the Nile, which comes down from Ethiopia into Egypt. The name of the third is Tigris, and of the fourth, Euphrates.”

“חדקל TIGRIS — It is called חדקל because its waters are pungent in taste (חד) and light in weight (קל) (Berakhot 59b). פרת EUPHRATES — It is called פרת because its waters grow (פרה) and increase and make men healthy (Berakhot 59b). כוש ואשור CUSH AND ASHUR did not then exist as countries, but Scripture writes with reference to the names which those districts would bear in the future (Ketubot 10b; Genesis Rabbah 16). קדמת אשור means AT THE EAST OF ASHUR. הוא פרת IS THE EUPHRATES — the most important of all, being mentioned in connection with the Land of Israel (Genesis Rabbah 16:3).”

“The name of the third river is Hiddekel,.... A river which ran by Shushan in Persia, and retained its name in the times of Daniel, Dan 10:4 where it is called the great river; and it seems it bears the same name now among the Persians; at least it did an hundred and fifty years ago, when Rauwolff (m) travelled in those parts. The Targum of Jonathan here calls it Diglath, the same with the Diglito of Pliny (n); and according to him it is called Tigris, from its swiftness, either from the tiger, a swift creature, or from "to dart", in the Chaldee language; and so Curtius (o) says, that in the Persian language they call a dart "tigris": and with this agrees the word "Hiddekel", which in the Hebrew language signifies sharp and swift, as a polished arrow is; and Jarchi says it is so called, because its waters are sharp and swift: though this is contradicted by some modern travellers (p) who say it is a slower stream than the Euphrates, and is not only very crooked, and full of meanders, but also choked up with islands, and great banks of stone: that is it which goeth towards the east of Assyria: a country which had its name from Ashur, a son of Shem, Gen 10:11 it became a famous kingdom and monarchy, Nineveh was the metropolis of it, which was built on the river Tigris or Hiddekel; and, as before observed, it ran by Shushan in Persia; and so, as Diodorus Siculus (q) says, it passed through Media into Mesopotamia; and which very well agrees with its being, according to Moses, one of the rivers of Eden. Twelve miles up this river, from Mosul, near which Nineveh once stood, lies an island, called the island of Eden, in the heart of the Tigris, about ten English miles in circuit, and is said to be undoubtedly a part of paradise (r): and the fourth river is Euphrates: or "Phrat", as in the Hebrew tongue. Reland (s) seems rightly to judge, that the syllable "eu", prefixed to it, is the Persian "au" or "cu", which in that language signifies "water"; so that "Euphrates" is no other than "the water of Phrat", so called from the fruitfulness of it; for its waters, as Jarchi says, fructify, increase, and fatten the earth; and who rightly observes that these names, and so those of other rivers, and of the countries here mentioned, are named by a prolepsis or anticipation, these being the names they bore when Moses wrote; unless it may be thought to be the Hebrew "Hu, the, that Phrat"; and which the Greeks have made an "eu" of. (After the global destruction of Noah's flood, it is doubtful that the location of these rivers could be determined with any degree of certainty today. Ed.) (m) Travels, part. 2. c. 9. p. 159. ed.
