Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 3:1-5

“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.”
