'Tree of Life' in the Bible

And [in that garden] the Lord God caused to grow from the ground every tree that is desirable and pleasing to the sight and good (suitable, pleasant) for food; the tree of life was also in the midst of the garden, and the tree of the [experiential] knowledge (recognition) of [the difference between] good and evil.

And the Lord God said, “Behold, the man has become like one of Us (Father, Son, Holy Spirit), knowing [how to distinguish between] good and evil; and now, he might stretch out his hand, and take from the tree of life as well, and eat [its fruit], and live [in this fallen, sinful condition] forever”—

So God drove the man out; and at the east of the Garden of Eden He [permanently] stationed the cherubim and the sword with the flashing blade which turned round and round [in every direction] to protect and guard the way (entrance, access) to the tree of life.
