Genesis 3:22-24

GOD said, “The Man has become like one of us, capable of knowing everything, ranging from good to evil. What if he now should reach out and take fruit from the Tree-of-Life and eat, and live forever? Never—this cannot happen!” So GOD expelled them from the Garden of Eden and sent them to work the ground, the same dirt out of which they’d been made. He threw them out of the garden and stationed angel-cherubim and a revolving sword of fire east of it, guarding the path to the Tree-of-Life.
