John Wesley on 2 Corinthians 3:13

And we do not act as Moses did, who put a veil over his face - Which is to be understood with regard to his writings also. So that the children of Israel could not look steadfastly to the end of that dispensation which is now abolished - The end of this was Christ. The whole Mosaic dispensation tended to, and terminated in, him; but the Israelites had only a dim, wavering sight of him, of whom Moses spake in an obscure, covert manner.
