The tree of life (Heb. עץ החיים Etz haChayim) in the Book of Genesis is a tree planted by God in midst of the Garden of Eden (Paradise), whose fruit gives everlasting life, i.e. immortality. Together with the tree of life, God planted the tree of the knowledge of good and evil (Genesis 2:9). According to some scholars, however, these are in fact two names for the same tree. According to the Encyclopædia Britannica, both are forms of the world tree.
