John Wesley on Exodus 33:18

I beseech thee shew me thy glory - Moses had lately been in the mount with God, and had had as intimate communion with God, as ever any man had on this side heaven, and yet he is still desiring a farther acquaintance. Shew me thy glory - Make me to see it; so the word is: make it some way or other visible, and enable me to bear the sight of it. Not that he was so ignorant as to think God's essence could be seen with bodily eyes, but having hitherto only heard a voice out of a pillar of cloud or fire, he desired to see some representation of the divine glory, such as God saw fit to gratify him with.
