Stretched out arm
A 'stretched out arm,' as in Exodus 6:6, signifies omnipotence or divine power, because 'an arm,' when stretched out in the heavens, represents power from the divine, but when not stretched out, but bended, it represents power in the general sense. This is why divine power is often shown in the Word as a stretched out arm or a strong hand.

Ezekiel 20:8-13
8
But they rebelled against me, and would not listen to me; they did not every man cast away the abominations of their eyes, neither did they forsake the idols of Egypt. Then I said I would pour out my wrath on them, to accomplish my anger against them in the midst of the land of Egypt.
9
But I worked for my name's sake, that it should not be profaned in the sight of the nations, among which they were, in whose sight I made myself known to them, in bringing them forth out of the land of Egypt.
10
So I caused them to go forth out of the land of Egypt, and brought them into the wilderness.
11
I gave them my statutes, and showed them my ordinances, which if a man does, he shall live in them.
12
Moreover also I gave them my Sabbaths, to be a sign between me and them, that they might know that I am Yahweh who sanctifies them.
13
But the house of Israel rebelled against me in the wilderness: they didn't walk in my statutes, and they rejected my ordinances, which if a man keep, he shall live in them; and my Sabbaths they greatly profaned. Then I said I would pour out my wrath on them in the wilderness, to consume them.
