genesis 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: - Free Bible Online

      22. And God said, Behold, the man is become as one of us--not spoken in irony as is generally supposed, but in deep compassion. The words should be rendered, "Behold, what has become [by sin] of the man who was as one of us"! Formed, at first, in our image to know good and evil--how sad his condition now.
      and now, lest he put forth his hand, and take also of the tree of life--This tree being a pledge of that immortal life with which obedience should be rewarded, man lost, on his fall, all claim to this tree; and therefore, that he might not eat of it or delude himself with the idea that eating of it would restore what he had forfeited, the Lord sent him forth from the garden.
