Adam Clarke on Exodus 16:7

Ye shall see the glory of the Lord - Does it not appear that the glory of the Lord is here spoken of as something distinct from the Lord? for it is said He (the glory) heareth your murmurings against the Lord; though the Lord may be here put for himself, the antecedent instead of the relative. This passage may receive some light from Heb 1:3 : Who being the brightness of his glory, and the express image of his person, etc. And as St. Paul's words are spoken of the Lord Jesus, is it not likely that the words of Moses refer to him also? "No man hath seen God at any time;" hence we may infer that Christ was the visible agent in all the extraordinary and miraculous interferences which took place both in the patriarchal times and under the law.
