Exodus 33:18 - Matthew Poole's English Annotations on the Holy Bible

i.e. Thy glorious majesty, the brightness of thy countenance, some such manifestation of thyself as becomes thy excellency, and such as shall be seen in the other life; or that glorious shape which, together with a human voice, thou hast now assumed. But for the essence of God, as that was and is and ever will be invisible to bodily eyes, 1 Timothy 6:16, so a man of such great reason and deep knowledge in Divine things, and universal learning, could not be ignorant of it, and therefore would not desire it.
