Because they knew that they had done amiss; or because the bright cloud had covered them; or because they had heard the voice of God the Father speaking; for human frailty cannot endure to look upon so great glory, and falls to the earth trembling through both soul and body. And by how much higher any one has aimed, by so much lower will be his fall, if he shall be ignorant of his own measure.
