'Arm' in the Bible

"And also, with respect to the foreigner, he who [is] not of your people Israel, but comes from a distant land, for the sake of your great name and your powerful hand and outstretched arm, when he comes and prays to this house,

With him [is] the arm of flesh, and with us [is] Yahweh our God, to help us and to fight our battles." And the people took confidence with the words of Hezekiah, king of Judah.
