'Arm' in the Bible

As far as this matter, may Yahweh pardon your servant when my master goes [into] the house of Rimmon to worship there, and he [is] leaning himself on my arm, that I also bow down [in] the house of Rimmon: when I bow down [in] the house of Rimmon, may Yahweh please pardon your servant in this matter."

Rather, Yahweh, who brought you out from the land of Egypt with great strength and with an outstretched arm--him you shall fear, and to him you shall bow down, and to him you shall sacrifice.
