Ezekiel 38:15-16

15You will 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 host, a mighty army.

16You will come up against my people Israel, like a cloud covering the land. In the latter days I will bring you against my land, that the nations may know me, when through you, O Gog, I vindicate my holiness before their eyes.
