And thou shalt come up against my people of Israel, as a cloud to cover the land; it shall be in the latter days, and I will bring thee against my land, that the heathen may know me, when I shall be sanctified in thee, O Gog, before their eyes.
The dream is doubled because the thing is certain and demands careful regard. God lets men know of Israel's security, their easy prey, their careless rest, yet He knows they will misuse that knowledge for their own ruin; their safety is real, grounded in His protection, and no weapon formed against them shall prosper.

Commenting on Ezekiel 38:14-23
Thus saith the Lord God,.... Putting the question that follows: art thou he of whom I have spoken of old time by my servants the prophets of Israel, which prophesied in those days many years that I will bring thee against them? certainly thou art he: but who were the prophets that prophesied of Gog before Ezekiel, since he is the first that makes mention of him?
I will bring thee against my land, that the heathen may know me--So in Exo 9:16, God tells Pharaoh, "For this cause have I raised thee up, for to show in thee My power; and that My name may be declared throughout all the earth."
