The Biblical account states that Adam and Eve were exiled from the Garden of Eden after eating from the tree of the knowledge of good and evil to prevent them from eating from the tree of life:
“ And the Lord God said, "The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever." (Genesis 3:22)[3] ”
By questioning God's word and authority, the serpent, who is regarded as Satan in Christianity but not in Judaism, initially tempted Eve into eating fruit from the tree of the knowledge of good and evil, an act explicitly forbidden by God. The serpent tempted Eve by suggesting that eating the fruit would cause her to become as wise as God, having knowledge of good and evil. Eve ate the fruit, against God's command to Adam and later so did Adam, despite God's warning that "in the day that you eat from it you shall surely die" (Genesis 2:17). As a consequence of their transgression, the land, the Serpent, Adam, and Eve were each cursed by God. To prevent them access to the tree of life God separated them from the tree of life, casting them out of the Garden. The banishment from the Garden of Eden is balanced in the New Testament by the planting of the tree of life on mankind's side of the divide.[citation needed]
In the Book of Revelation, a Koine Greek phrase xylon zoës (ξύλον ζωής) is mentioned 3 times. This phrase, which literally means "wood of life" is translated in nearly every English Bible version as "tree of life", see Revelation 2:7, 22:2, and 22:19.
