Genesis 2:10-14

10And a river went out of Eden, to water the garden; and from thence it was parted, and became four main streams.

11The name of the one is Pison: that is it which surrounds the whole land of Havilah, where the gold is.

12And the gold of that land is good; bdellium and the onyx stone are there.

13And the name of the second river is Gihon: that is it which surrounds the whole land of Cush.

14And the name of the third river is Hiddekel: that is it which flows forward toward Asshur. And the fourth river, that is Euphrates.
