The New John Gill Exposition of the Entire BibleGenesis 2:13
And the name of the second river [is] Gihon…
was one of this name in the land of Israel, which, or a branch of it,
flowed near Jerusalem, (1 Kings 1:33) (2 Chronicles 32:30) this Aben Ezra
suggests is here meant, and which favours the notion of the above
learned man, that the garden of Eden was in the land of Israel.
Josephus F8 takes it to be the river Nile, as do many others; it
seems to have been a branch of the river Euphrates or Tigris, on the
eastern side, as Phison was on the west; and so Aben Ezra says it
came from the south east. The learned Reland F9 will have it to be
the river Araxes: it has its name, according to Jarchi, from the
force it goes with, and the noise it makes. And it seems to have its
name from (xwg) , which signifies to come forth with great force, as
this river is said to do, when it pours itself into the Baltic sea.
The same [is] it that compasseth the whole land of Ethiopia;
either Ethiopia above Egypt; and this favours the notion of those who
take Gihon to be the Nile: for Pausanias F11 says, that it was
commonly reported that the Nile was Euphrates, which disappearing in
a marsh, rose up above Ethiopia, and became the Nile, and so washed
that country, and is thought to agree very well with the Mosaic
account: or else that Cush or Ethiopia, which bordered on Midian, and
was a part of Arabia, and may be called Arabia Chusea, often meant by
Cush in Scripture. Reland F12 thinks the country of the Cossaeans or
Cussaeans, a people bordering on Media, the country of Kuhestan, a
province of Persia, is intended.
(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
