Catena Aurea · Lukasevangelium 6
And it came to pass also on another sabbath, that he entered into the synagogue and taught: and there was a man whose right hand was withered. And the Scribes and Pharisees watched him, whether he would heal on the sabbath day; that they might find an accusation against him. But he knew their thoughts, and said to the man which had the withered hand, Rise up, and stand forth in the midst. And he arose and stood forth. Then said Jesus unto them, I will ask you one thing; Is it lawful on the sabbath days to do good, or to do evil? to save life, or to destroy it? And looking round about upon them all, he said unto the man, Stretch forth thy hand. And he did so: and his hand was restored whole as the other. And they were filled with madness; and communed one with another what they might do to Jesus.
You have heard then the words of Him who says, Stretch forth thy hand. That is a frequent and common cure, and thou that thinkest thy hand is whole, beware lest it be contracted by avarice or sacrilege. Stretch it forth oftener to help thy neighbour, to protect the widow, to save from injury him whom you see the victim of unjust attack; stretch it forth to the poor man who beseeches thee; stretch it forth to the Lord, to ask pardon of thy sins; as the hand is stretched forth so is it healed. (1 Kings 13:5, 6.)
