Ezekiel 38:14-16

14“Therefore prophesy, son of man, and say to Gog, ‘This is what the Lord God says: On that day when my people Israel are dwelling securely, will you not know this

15and come from your place in the remotest parts of the north  — you and many peoples with you, who are all riding horses — a huge assembly, a powerful army?

16You will advance against my people Israel like a cloud covering the land. It will happen in the last days, Gog, that I will bring you against my land so that the nations may know me, when I demonstrate my holiness through you in their sight.
