Genesis 2:10–14

10 A river flowed out of Eden to water the garden, and there it divided and became four rivers. 11 The name of the first is the Pishon. It is the one that flowed around the whole land of Havilah, where there is gold. 12 And the gold of that land is good; bdellium and onyx stone are there. 13 The name of the second river is the Gihon. It is the one that flowed around the whole land of Cush. 14 And the name of the third river is the Tigris, which flows east of Assyria. And the fourth river is the Euphrates.
