ANSWER: a withered hand
And He entered again into a synagogue; and a man was there with a withered hand . And they were watching Him to see if He would heal him on the Sabbath, in order that they might accuse Him. And He said to the man with the withered hand, "Rise and come forward!" And He said to them, "Is it lawful on the Sabbath to do good or to do harm, to save a life or to kill?" And after looking around at them with anger, grieved at their hardness of heart, He said to the man, "Stretch out your hand." And he stretched it out, and his hand was restored.
