'Arm' in the Bible

And the Lord said to Moses, Now you will see what I am about to do to Pharaoh; for by a strong hand he will be forced to let them go, driving them out of his land because of my outstretched arm.

Say then to the children of Israel, I am Yahweh, and I will take you out from under the yoke of the Egyptians, and make you safe from their power, and will make you free by the strength of my arm after great punishments.

Fear and grief came on them; by the strength of your arm they were turned to stone; till your people went over, O Lord, till the people went over whom you have made yours.
