Gen 2:10-14

10A river flows out of Eden to water the garden, and from there it divides and becomes four branches.11The name of the first is Pishon; it is the one that flows around the whole land of Havilah, where there is gold;12and the gold of that land is good; bdellium and onyx stone are there.13The name of the second river is Gihon; it is the one that flows around the whole land of Cush.14The name of the third river is Tigris, which flows east of Assyria. And the fourth river is the Euphrates.
