John Chrysostom

For since he said that in the reading of the Old Testament the veil remaineth, lest any should think that this that is said is from the obscurity of the Law, he both by other things showed even before what his meaning was, (for by saying, "their minds were hardened," he shows that the fault was their own,) and, in this place too, again. For he said not, 'The veil remaineth on the writing,' but "in the reading;" (now the reading is the act of those that read;) and again, "When Moses is read." He showed this however with greater clearness in the expression which follows next, saying unreservedly, "The veil lieth upon their heart." For even upon the face of Moses it lay, not because of Moses, but because of the grossness and carnal mind of these.
