Ezekiel 38:16, 23

You will advance against my people Israel like a cloud that covers the land. In days to come, Gog, I will bring you against my land, so that the nations may know me when I am proved holy through you before their eyes.

And so I will show my greatness and my holiness, and I will make myself known in the sight of many nations. Then they will know that I am the LORD.’
