Genesis 2:9-14

The LORD God made all sorts of trees grow up from the ground—trees that were beautiful and that produced delicious fruit. In the middle of the garden he placed the tree of life and the tree of the knowledge of good and evil. A river flowed from the land of Eden, watering the garden and then dividing into four branches. The first branch, called the Pishon, flowed around the entire land of Havilah, where gold is found. The gold of that land is exceptionally pure; aromatic resin and onyx stone are also found there. The second branch, called the Gihon, flowed around the entire land of Cush. The third branch, called the Tigris, flowed east of the land of Asshur. The fourth branch is called the Euphrates.
