Genesis 2:9-14

Out of the ground the LORD God caused to grow every tree that is pleasing to the sight and good for food; the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil. Now a river flowed out of Eden to water the garden; and from there it divided and became four rivers. The name of the first is Pishon; it flows around the whole land of Havilah, where there is gold. The gold of that land is good; the bdellium and the onyx stone are there. The name of the second river is Gihon; it flows around the whole land of Cush. The name of the third river is Tigris; it flows east of Assyria. And the fourth river is the Euphrates.
