"The glory that shone on the face of Moses was a reflection of the righteousness of Christ in the law. The law itself would have no glory, only that in it Christ is embodied. It has no power to save. It is lusterless only as in it Christ is represented as full of righteousness and truth."PP
And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him.
Exodus 34:30
