Ezekiel 38:15-16

151You will come from your place out of the remote parts of the north, you and many peoples with you, all of them riding horses, a large assembly and a mighty army; 16and you will come up against My people Israel like a cloud to cover the land. It shall come about in the last days that I will bring you against My land, so that the nations may 2know Me when I 3show Myself holy through you before their eyes, Gog.”
