Genesis 2:10-14

10Now a river flowed out of Eden to water the garden; and from there it divided and became four [branching] rivers.

11The first [river] is named Pishon; it flows around the entire land of Havilah, where there is gold.

12The gold of that land is good; bdellium (a fragrant, valuable resin) and the onyx stone are found there.

13The name of the second river is Gihon; it flows around the entire land of Cush [in Mesopotamia].

14The third river is named Hiddekel (Tigris); it flows east of Assyria. And the fourth river is the Euphrates.
