"According to Gen. ii. 9, there stood in the midst of the Garden of Eden a "tree of life," apparently by the side of the "tree of knowledge of good and evil." Although Gen. iii. 3 seems to presuppose but one tree there, Gen. iii. 22 asserts that, after the primitive pair had eaten of the tree of knowledge, they were expelled from Eden lest they should put forth their hands and take of the tree of life and live forever. The view of the writer was that Eden contained a tree the magical power of the fruit of which conferred immortality upon him who partook of it, though Yhwh prohibited mortals from partaking of this fruit."
