Ezekiel 38:14-16

14“Therefore, son of man, prophesy and say to Gog: ‘This is what the Sovereign Lord says: In that day, when my people Israel are living in safety, will you not take notice of it?

15You will come from your place in the far north, you and many nations with you, all of them riding on horses, a great horde, a mighty army.

16You will advance against my people Israel like a cloud that covers the land. In days to come, Gog, I will bring you against my land, so that the nations may know me when I am proved holy through you before their eyes.
