Ezekiel 38:16, 23

and thou shalt come up against my people Israel, as a cloud to cover the land: it shall come to pass in the latter days, that I will bring thee against my land, that the nations may know me, when I shall be sanctified in thee, O Gog, before their eyes.

And I will magnify myself, and sanctify myself, and I will make myself known in the eyes of many nations; and they shall know that I am Jehovah.
