2 Corinthians 12:4

How that he was caught up into (c) paradise, and heard (d) unspeakable words, which it is not (e) lawful for a man to utter.

(c) So the Greeks name that which we call a park, that is to say, a place where trees are planted, and wild beasts kept. And those that translated the Old Testament out of Hebrew into Greek, called the garden of Eden by this name, into which Adam was put immediately after his creation, as a most delicate and pleasant place. And from this it occurred that the blessed seat of the glory of God is called by that name.

(d) Which no man is able to utter.

(e) Which the saints themselves are not by any means able to express, because it is God himself. This is the way that Clement of Alexandria explains this passage, Strom. 5.
