Thematic Bible: Watered by a river

Now a river flowed out from Eden that watered the garden, and from there it diverged and became four branches. The name of the first [is] the Pishon. It went around all the land of Havilah, where [there is] gold. (The gold of that land [is] good; bdellium and onyx stones [are] there.) read more.
And the name of the second [is] Gihon. It went around all the land of Cush. And the name of the third [is] Tigris. It flows east of Assyria. And the fourth river [is] the Euphrates.
