(gug=darkness).
1- In Ez. chaps, 38 and 39, Gog is a prince in the land of Magog, who will invade, like a whirlwind, Israel.
(38:9). But, by Yahweh’s hand, he will fall on the mountains of Israel, with all his armies and nations that follow him (39:4).
2- In Rev 20:7-9, it appears again: After the millennium, Satan will be released, and he will go out to mislead all the nations of the earth, and he will gather an army like the sands of the sea, which will surround the “camp of the saints and the beloved city”. But fire will come down from heaven and devour them. He is the Antichrist of the end times!

In Ez. 38.2 we read about “Gog in the land of Magog, sovereign prince of *Meshech and Tubal” (°vrv2; °vrv1 “prince of the head”; °nbe “champion and leader”; °vm “prince of *Ros, Meshech and Tubal”). The LXX he interpreted that Magog was a people and not a country. The only reasonable comparison of Gog is with Gyges, king of Lydia (ca. 660 BC), as. Gugu; Magog could be the ace.mā
Since we need not interpret that Ez. 38–39 predates Ez. 40–48, and since the rabbinical tradition places Gog after the time of the Messiah, we need not necessarily see a contradiction between Ezekiel and Revelation, provided that we understand the millennium in the sense that the rabbis gave to “the days of the Messiah” .

Names, respectively, of a king and his supposed kingdom, mentioned several times in Ezekiel 38 and 39, and once in the Apocalypse (20,7). In the first passage of Ezekiel we read Yahweh’s order to the prophet: “Son of man, turn your face towards Gog, in the country of Magog,… and prophesy against him… You will say, Here I am against you, O Gog, supreme prince of Meshek and Tubal.” (38.2-3). A similar order is also found at the beginning of chapter 39. These two chapters contain repeated references to Gog and Magog, but provide only vague and uncertain indications as to the identity of the ruler or the location of the country. In the chap. 38:5-6 Gog is represented as being accompanied in his invasion of the land of Israel by the Persians, Ethiopians and Libyans, Gomer and… the house of Bet Torgamá; and in verse 15 we read: “You will come from your place, from the far north.”
From the number and variety of peoples mentioned in this connection some writers have inferred that the name Gog is only a generic appellation, or figure, used by Ezekiel to designate the army of Israel’s enemies; and in the Apocalypse to denote the multitude of the enemies of the Church. Others conjecture that it may be the local title expressing royal dignity, such as the name of Pharaoh in Egypt. But it seems more likely that both names are historical; and some scholars identify Gog with the Lydian king called Gyges by the Greeks, who appears as Gu-gu in Assyrian inscriptions. If this is true, Magog could be identified with Lydia. On the other hand, since Mések and Túbal were cities belonging to Asia Minor, it would seem from Ezekiel’s text that Magog must have been in that part of the world. Finally, Flavius Josephus and others identify Magog with Scythia, but in ancient times this name was used loosely to designate any northern town.
