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:

Genesis 2:17

But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die [dying you shall die].

Genesis 2:9

And out of the ground made the LORD God 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 knowledge of good and evil.
