Genesis 2:12

And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads.

The name of the first [is] Pison: that [is] it which compasseth the whole land of Havilah, where [there is] gold;

And the name of the second river [is] Gihon: the same [is] it that compasseth the whole land of Ethiopia.

And the name of the third river [is] Hiddekel: that [is] it which goeth toward the east of Assyria. And the fourth river [is] Euphrates.
