'Arms' in the Bible

He makes my hands expert in war, so that a bow of brass is bent by my arms.

For the arms of the evil-doers will be broken: but the Lord is the support of the good.

For they did not make the land theirs by their swords, and it was not their arms which kept them safe; but your right hand, and your arm, and the light of your face, because you had pleasure in them.

It sent out its arms to the Sea, and its branches to the River.
