Ezekiel 38:15-16
15
You shall come from your place out of the uttermost parts of the north, you, and many peoples with you, all of them riding on horses, a great company and a mighty army;
16
and you shall come up against my people Israel, as a cloud to cover the land: it shall happen in the latter days, that I will bring you against my land, that the nations may know me, when I shall be sanctified in you, Gog, before their eyes.
