Genesis 2:10-15 New Revised Standard Version (NRSV)
10 A river flows out of Eden to water the garden, and from there it divides and becomes four branches. 11 The name of the first is Pishon; it is the one that flows 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 Gihon; it is the one that flows around the whole land of Cush. 14 The name of the third river is Tigris, which flows east of Assyria. And the fourth river is the Euphrates.
15 The Lord God took the man and put him in the garden of Eden to till it and keep it.
