'Arm' in the Bible

And as for the man from a strange land, who is not of your people Israel but comes from a far country because of the glory of your name and your strong hand and your outstretched arm; when he comes to make his prayer, turning to this house:

Then they made the king's son come out, and they put the crown on his head and gave him the arm-bands and made him king: and Jehoiada and his sons put the holy oil on him and said, Long life to the king.

With him is an arm of flesh; but we have the Lord our God, helping us and fighting for us. And the people put their faith in what Hezekiah, king of Judah, said.
