and behold, a man having a withered hand. And they asked him, saying, Is it lawful to heal on the sabbath day? that they might accuse him.

And the scribes and the Pharisees watched him, whether he would heal on the sabbath; that they might find how to accuse him.

And Jesus answering spake unto the lawyers and Pharisees, saying, Is it lawful to heal on the sabbath, or not?
