Genesis 2:8-10

And Jehovah God planted a garden eastward, in Eden; and there he put the man whom he had formed. And out of the ground made Jehovah God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil. And a river went out of Eden to water the garden; and from thence it was parted, and became four heads.
