Then he said to the man,
Stretch forth your hand.
And he stretched it forth; and it was restored whole, like the other.

AD 856
Jesus teaches and works chiefly on the sabbath, not only on account of the spiritual sabbath, but on account of the gathering together of the people, seeking that all should be saved.
Otherwise; The man who had the withered hand denotes the human race in its barrenness of good works dried up by the hand which was stretched out to the fruit; this was healed by the stretching out of the innocent hand on the Cross.
