See this explained in Matthew 12:9-13.

A man there which had a withered hand - See this explained on Matthew 12:10 (note), etc., and on Luke 6:6, Luke 6:10 (note).

And he entered again into the synagogue,.... Perhaps in Capernaum, where he had before cast out the unclean spirit; but not on the same day, nor on that day he had had the debate with the Pharisees, about his disciples plucking the ears of corn on the sabbath day; but on another sabbath, perhaps the next; see Luke 6:6.

And there was a man there which had a withered hand; who came there either for a cure, knowing Christ to be in the synagogue, or for the sake of worship; See Gill on Matthew 12:10.

A withered hand (ἐξηραμμένην τὴν χεῖρα)

More correctly Rev., his hand withered. The participle indicates that the withering was not congenital, but the result of accident or disease. Luke says his right hand.

And {1} he entered again into the synagogue; and there was a man there which had a {a} withered hand.

(1) Thirdly, because they preferred the ceremonial law (which was but an addition to the moral law) before the moral law, whereas in reality they should have learned from this the true use of the ceremonial law.

(a) That is, unprofitable and dead.

CHAPTER 3

Mr 3:1-12. The Healing of a Withered Hand on the Sabbath Day, and Retirement of Jesus to Avoid Danger. ( = Mt 12:9-21; Lu 6:6-11).

See on [1411]Mt 12:9-21.

3:1-5 This man's case was piteous; he had a withered hand, which disabled him from working for his living; and those that are so, are the most proper objects of charity. Let those be helped that cannot help themselves. But stubborn infidels, when they can say nothing against the truth, yet will not yield. We hear what is said amiss, and see what is done amiss; but Christ looks at the root of bitterness in the heart, the blindness and hardness of that, and is grieved. Let hard-hearted sinners tremble to think of the anger with which he will look upon them shortly, when the day of his wrath comes. The great healing day now is the sabbath, and the healing place the house of prayer; but the healing power is of Christ. The gospel command is like that recorded here: though our hands are withered, yet, if we will not stretch them out, it is our own fault that we are not healed. But if we are healed, Christ, his power and grace, must have all the glory.
