Ezekiel 38:14-17

Therefore, son of man, prophesy, and say unto Gog, Thus saith the Lord Jehovah: In that day when my people Israel dwelleth securely, shalt thou not know it? And thou shalt come from thy place out of the uttermost parts of the north, thou, and many peoples with thee, all of them riding upon horses, a great company and a mighty army; 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. Thus saith the Lord Jehovah: Art thou he of whom I spake in old time by my servants the prophets of Israel, that prophesied in those days for many years that I would bring thee against them?
