10 And there was a man with a dead hand. And they put a question to him, saying, Is it right to make a man well on the Sabbath day? so that they might have something against him. 11 And he said to them, Which of you, having a sheep, if it gets into a hole on the Sabbath day, will not put out a helping hand and get it back? 12 Of how much more value is a man than a sheep! For this reason it is right to do good on the Sabbath day. 13 Then said he to the man, Put out your hand. And he put it out, and it was made as well as the other.

Commentary on Matthew 12:9-13
(Read Matthew 12:9-13)
Christ shows that works of mercy are lawful and proper to be done on the Lord's day. There are more ways of doing well upon sabbath days, than by the duties of worship: attending the sick, relieving the poor, helping those who need speedy relief, teaching the young to care for their souls; these are doing good: and these must be done from love and charity, with humility and self-denial, and shall be accepted, Genesis 4:7. This, like other cures which Christ wrought, had a spiritual meaning. By nature our hands are withered, and we are unable of ourselves to do any thing that is good. Christ only, by the power of his grace, cures us; he heals the withered hand by putting life into the dead soul, works in us both to will and to do: for, with the command, there is a promise of grace given by the word.
