'Arm of the Lord' in the Bible

Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon?

Who hath believed our report? and to whom is the arm of the LORD revealed?

Now for all the Signs he had performed before them, they did not believe in him ??38 that the word spoken by the prophet Isaiah might be fulfilled: Lord, who has believed what they heard from us, And to whom has the arm of the Lord been revealed?

That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
