'Arm' in the Bible

And as to the stranger also, who is not of thy people Israel, but cometh out of a far country for thy great name's sake, and thy mighty hand and thy stretched-out arm; when they shall come and pray toward this house,

with him is an arm of flesh, but with us is Jehovah our God to help us and to fight our battles. And the people depended upon the words of Hezekiah king of Judah.
