Gen 3:22-23 (AKJV/PCE)
(3:22) ¶ And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever: (3:23) Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
