Genesis 2:10-14
A river watering the garden flowed from Eden; from there it was separated into four headwaters.
The name of the first is the Pishon; it winds through the entire land of Havilah, where there is gold.(The gold of that land is good; aromatic resin and onyx are also there.)
The name of the second river is the Gihon; it winds through the entire land of Cush.
The name of the third river is the Tigris; it runs along the east side of Ashur.
And the fourth river is the Euphrates.
