'Arm' in the Bible

"How have you helped him who is without power! How have you saved the arm that has no strength!

then let my shoulder fall from the shoulder blade, and my arm be broken from the bone.

"By reason of the multitude of oppressions they cry out. They cry for help by reason of the arm of the mighty.

From the wicked, their light is withheld. The high arm is broken.

Or do you have an arm like God? Can you thunder with a voice like him?
