Ezekiel 38:16-17

You will come up against My people Israel like a cloud, to cover the land. It will be in the latter days that I will bring you against My land, so that the nations may know Me, when I am hallowed in you, O Gog, before their eyes.” Thus says the Lord GOD: “Are you he of whom I have spoken in former days by My servants the prophets of Israel, who prophesied for years in those days that I would bring you against them?
