Genesis 2:9-13

Out of the ground the Lord God caused every tree to grow that is pleasing to the sight and good for food; the tree of life was 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 as well.

The name of the second river is Gihon; it flows around the whole land of Cush.
