'Arm' in the Bible

Therefore say to the {Israelites}, 'I [am] Yahweh, and I will bring you out from under the {forced labor} of Egypt, and I will deliver you from their slavery, and I will redeem you with an outstretched arm and with great punishments.

Terror and dread fell on them; at the greatness of your arm they became silent like the stone, until your people passed by, Yahweh, until [the] people whom you bought passed by.
