Genesis 2:8-10

Then the LORD God planted a garden in the east, in a place called Eden, and put the man he had formed into it. The LORD God caused every beautiful tree and every tree that was good for food to grow out of the ground. In the middle of the garden, God put the tree that gives life and also the tree that gives the knowledge of good and evil. A river flowed through Eden and watered the garden. From there the river branched out to become four rivers.
