Ezekiel 38:14-16

14Therefore, son of man, prophesy and say unto Gog, Thus saith the Lord Yhwh; In that day when my people of Israel dwelleth safely, shalt thou not know it? 15And thou shalt come from thy place out of the north parts, thou, and many people with thee, all of them riding upon horses, a great company, and a mighty army: 16And thou shalt come up against my people of Israel, as a cloud to cover the land; it shall be in the latter days, and I will bring thee against my land, that the heathen may know me, when I shall be sanctified in thee, O Gog, before their eyes.
