Genesis 2:10-14

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