Ezekiel 38:16, 23

and you will go up against My people Israel like a cloud to cover the land. In the last days it will come about that I will bring you against My land, so that the nations may know Me when I show Myself holy through you before their eyes, O Gog.”

Thus I shall magnify Myself and demonstrate My greatness and sanctify Myself, and I will be recognized and will make Myself known in the sight of many nations; they will know [without any doubt] that I am the LORD.” ’
