Matthew 12:13

Then saith he to the man. — St. Mark, with his usual vividness, adds the look and gesture and feeling which accompanied the words, “looking round about on them with anger, being grieved at the hardness of their hearts.”

It was restored whole — i.e., as the tense implies, in the act of stretching the hand forth. The man’s ready obedience to the command, which if he had not believed in the power of Jesus would have seemed an idle mockery, was, ipso facto, a proof that he had “faith to be healed.”
