Is the arm of the lord Jesus?
Exodus 6:6
Say therefore to the people of Israel, ‘I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will deliver you from slavery to them, and I will redeem you with an outstretched arm and with great acts of judgment.
Exodus 15:16
Terror and dread fall upon them; because of the greatness of your arm, they are still as a stone, till your people, O Lord, pass by, till the people pass by whom you have purchased.
