Luke 6:10

When the eyes of all were, as it were, riveted together, and their minds also fixed upon the consideration of the matter, he said to the man, Stretch forth thy hand; I command thee, Who created man. But he who had the withered hand hears, and is made whole, as it follows, And he stretched it, and it was restored.

You have heard then the words of Him who says, Stretch forth thy hand. That is a frequent and common cure, and thou that thinkest thy hand is whole, beware lest it be contracted by avarice or sacrilege. Stretch it forth oftener to help thy neighbour, to protect the widow, to save from injury him whom you see the victim of unjust attack; stretch it forth to the poor man who beseeches thee; stretch it forth to the Lord, to ask pardon of thy sins; as the hand is stretched forth so is it healed. (1 Kings 13:5, 6.)

Thou perceivest, O Pharisee, a divine Worker, and Him Who delivers the sick by His heavenly power, and out of envy thou breathest forth death.

The man represents the human race, withered by the unfruitfulness of good works, because of the hand in our first parent stretched forth to take the apple, which was healed by the innocent hand stretched forth on the cross. And rightly was the withered hand in the synagogue, because where there is the greater gift of knowledge, there the transgressor lies under the greater blame.

But the law by things present prefigured the form of things future, among which surely the days of rest to come are to be not from good works but from evil. For although secular works may be given up, yet it is no idle act of a good work to rest in the praise of God.
