Genesis 2:10

8The LORD God planted a garden eastward, in Eden, and there he put the man whom he had formed.

9Out of the ground the LORD God made every tree to grow that is pleasant to the sight, and good for food, including the tree of life in the middle of the garden and the tree of the knowledge of good and evil.

10A river went out of Eden to water the garden; and from there it was parted, and became the source of four rivers.

11The name of the first is Pishon: it flows through the whole land of Havilah, where there is gold;

12and the gold of that land is good. Bdellium and onyx stone are also there.
