Ezekiel Chapter 39 Vs. 2

Prophesy against Gog

And I will turn thee back, and leave but the sixth part of thee, and will cause thee to come up from the north parts, and will bring thee upon the mountains of Israel: Eze. 39:2

I will turn... When Gog comes into Israel this time he will be turned back and completely destroyed. The result will not be thus when he invades Israel 3 1/2 years earlier (in the middle of Daniel’s 70th week) to take over Jerusalem and the Jewish temple as his capital (Dan. 9:27; Mat. 24:51; 2Th. 2:3-4; Rev. 11:1-2; 13:1-18). God will permit him to drive the Jews out of Israel and occupy their country for about 3 1/2 years in the last part of the 7-year tribulation period. Then, during this time He will raise up new enemies north and east of Gog’s 10 kingdoms to keep him occupied in war so that he cannot concentrate on the total destruction of Israel. At the end of these 3 1/2 years, after conquering these enemies, he will lead the nations against Israel and Jerusalem to do what he intended at the beginning; but before he can take all of Jerusalem he will be defeated by the second coming of Christ (Zec. 14:1-15; 2Th. 1:7-10; Jugs. 1:14-15; Rev. 19:11-21).

sixth part of... A sixth part of men under Antichrist being spared would mean about 166,667 escaping destruction and 833,333 being destroyed out of every million. We have no way of telling how many millions of men will be in the vast armies of the nations, but there will be many to fulfill Eze. 38:22; Rev. 14:20. This is the time he is to be turned back from his purpose and his armies are to be destroyed—all but a sixth part.

from the north... Antichrist’s army will come down from the north into Israel, as the Assyrians, Babylonians, Grecians, and others did in the past. Syria is north of Israel, and an army from Babylon would come west through that country and then south into Israel to avoid the desert.

This is a possible explanation of the details of the effect of God's attack upon them. It seems this vast army all die, except for one out of every six. This can’t be at the end of the Millennium because if it was all would be instantly killed.

The invading armies will be totally destroyed by God. Having brought them against the mountains of Israel (Eze. 39:2; cf. 38:8).
