'Arm' in the Bible

How have you given help to him who has no power! how have you been the salvation of the arm which has no strength!

May my arm be pulled from my body, and be broken from its base.

Because the hand of the cruel is hard on them, men are making sounds of grief; they are crying out for help because of the arm of the strong.

And from the evil-doers their light is kept back, and the arm of pride is broken.

Have you an arm like God? have you a voice of thunder like his?
