Ezequiel 38:16

16 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.

16 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.
