Theophylact of Ohrid
Catena Aurea · Markusevangelium 3
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. And he saith unto the man which had the withered hand, Stand forth. And he saith unto them, Is it lawful to do good on the sabbath days, or to do evil? to save life, or to kill? But they held their peace. And when he had looked round about on them with anger, being grieved for the hardness of their hearts, he saith unto the man, Stretch forth thine hand. And he stretched it out: and his hand was restored whole as the other.
Or, he has his right hand withered, who does not the works which belong to the right side; for from the time that our hand is employed in forbidden deeds, from that time it is withered to the working of good. But it will be restored whenever it stands firm in virtue; wherefore Christ saith, Arise, that is, from sin, and stand in the midst; that thus it may stretch itself forth neither too little or too much.
