And the Lord God planted a garden in Eden, in the east, and there he put the man whom he had formed. And out of the ground the Lord God made to spring up every tree that is pleasant to the sight and good for food. The tree of life was in the midst of the garden, and the tree of the knowledge of good and evil. - Genesis 2:8-9
Eden is in the east where God planted a garden with every tree that is pleasant to the sight and good for food and placed the first man. In the garden's midst is the tree of life and the tree of the knowledge of good and evil. Eden also contains a river from which the Pishon, Gihon, Tigris, and Euphrates flow.
(Genesis 2)
Because of Adam and Eve's sin, the LORD God drove them out of Eden. He placed the cherubim and a flaming sword that turned every way to guard the way to the tree of life, so that they may not also eat of its fruit and live forever.
(Genesis 3)
