Genesis 2:9-14

The LORD God caused every beautiful tree and every tree that was good for food to grow out of the ground. In the middle of the garden, God put the tree that gives life and also the tree that gives the knowledge of good and evil. A river flowed through Eden and watered the garden. From there the river branched out to become four rivers. The first river, named Pishon, flows around the whole land of Havilah, where there is gold. The gold of that land is excellent. Bdellium and onyx are also found there. The second river, named Gihon, flows around the whole land of Cush. The third river, named Tigris, flows out of Assyria toward the east. The fourth river is the Euphrates.
