Genesis 2:12

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

11The name of the first is Pison: that is it which compasseth the whole land of Havilah, where there is gold;

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

13And the name of the second river is Gihon: the same is it that compasseth the whole land of Ethiopia.

14And the name of the third river is Hiddekel: that is it which goeth toward the east of Assyria. And the fourth river is Euphrates.
