Genesis 2:8-10

⁸The Lord God planted a garden toward the east, in Eden; and there He placed the man whom He had formed. ⁹Out of the ground the Lord God caused every tree to grow that is pleasing to the sight and good for food; the tree of life was also in the midst of the garden, and the tree of the knowledge of good and evil.

¹⁰Now a river flowed out of Eden to water the garden; and from there it divided and became four rivers.
