10 and a man with a shriveled hand was there. Looking for a reason to bring charges against Jesus, they asked him, "Is it lawful to heal on the Sabbath?" 11 He said to them, "If any of you has a sheep and it falls into a pit on the Sabbath, will you not take hold of it and lift it out? 12 How much more valuable is a person than a sheep! Therefore it is lawful to do good on the Sabbath." 13 Then he said to the man, "Stretch out your hand." So he stretched it out and it was completely restored, just as sound 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.
