Mark 3:1

(ubi sup.) But mystically, the man with a withered hand shows the human race, dried up as to its fruitfulness in good works, but now cured by the mercy of the Lord; the hand of man, which in our first parent had been dried up when he plucked the fruit of the forbidden tree, through the grace of the Redeemer, Who stretched His guiltless hands on the tree of the cross, has been restored to health by the juices of good works. Well too was it in the synagogue that the hand was withered; for where the gift of knowledge is greater, there also the danger of inexcusable guilt is greater.

After confounding the Jews, who had blamed His disciples, for pulling the ears of corn on the sabbath day, by the example of David, the Lord now further bringing them to the truth, works a miracle on the sabbath; showing that, if it is a pious deed to work miracles on the sabbath for the health of men, it is not wrong to do on the sabbath things necessary for the body: he says therefore, And he entered again into the synagogue; and there was a man there which had a withered hand. And they watched him, whether he would heal him on the sabbath-day; that they might accuse him.
