6It also happened on another Sabbath, that he entered into the synagogue and taught. There was a man there, and his right hand was withered. 7The scribes and the Pharisees watched him, to see whether he would heal on the Sabbath, that they might find an accusation against him. 8But he knew their thoughts; and he said to the man who had the withered hand, "Rise up, and stand in the middle." He arose and stood. 9Then Jesus said to them, "I will ask you something: Is it lawful on the Sabbath to do good, or to do harm? To save a life, or to kill?" 10He looked around at them all, and said to him, "Stretch out your hand." He did, and his hand was restored as sound as the other.
