We read this interesting account of the expulsion of Adam and Eve from the Garden of Eden at Gen 3:24 :
He drove out the man; and at the east of the garden of Eden he placed the cherubim, and a sword flaming and turning to guard the way to the tree of life.
One wonders as for whom the guarding of the Tree of Life was intended. Adam and Eve had not been prohibited from eating from the Tree of Life, which was separate from the Tree of Knowledge ( Gen 2:9 and 2:17). With the bad experience with Tree of Knowledge,they were less likely to eat from the Tree of Life, even if given a chance. Were there other human beings around, who were likely to enter the garden and eat from the trees ? Was it possible that animals with a certain level of intelligence were also attracted to the trees ? ( Unfortunately, Chapter 3 ends with Verse 24 and Chapter 4 starts with an account of the birth of Cain and Abel).
My question therefore is : against whom was the Tree of Life guarded after the fall of Adam and Eve ?
