Genesis 2:9 + 3:22-24

2  9Out of the ground the Lord God made 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.

3  22Then the Lord God said, “See, the humans have become like one of us, knowing good and evil, and now they might reach out their hands and take also from the tree of life and eat and live forever”— 23therefore the Lord God sent them forth from the garden of Eden, to till the ground from which they were taken. 24He drove out the humans, and at the east of the garden of Eden he placed the cherubim and a sword flaming and turning to guard the way to the tree of life.
