Genesis 2:11-15

The name of the first is Pishon; it flows around the whole land of Havilah, where there is gold.

The gold of that land is good; the bdellium and the onyx stone are there as well.

The name of the second river is Gihon; it flows around the whole land of Cush.

The name of the third river is Tigris; it flows east of Assyria. And the fourth river is the Euphrates.

Then the Lord God took the man and put him in the Garden of Eden to cultivate it and tend it.
