Matthew Poole and continuators on Exodus 33:18

(i. e.)

But for the essence of God, as that was and is and ever will be invisible to bodily eyes, 1 Tim. 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.
