'Arm' in the Bible

On another Sabbath He had gone to the synagogue and was teaching there; and in the congregation was a man whose right arm was withered.

He knew their thoughts, and said to the man with the withered arm, "Rise, and stand there in the middle." And he rose and stood there.

And looking round upon them all He said to the man, "Stretch out your arm." He did so, and the arm was restored.
