“Therefore, son of man, prophesy, and say to Gog, Thus says the Lord GOD: On that day when my people Israel are dwelling securely, will you not know it?
The dream is doubled because the thing is certain and demands careful regard. God lets men know of Israel's security, their easy prey, their careless rest, yet He knows they will misuse that knowledge for their own ruin; their safety is real, grounded in His protection, and no weapon formed against them shall prosper.

Commenting on Ezekiel 38:14-23
Gog comes from the far north, from Scythia or Cathaia in Tartary, bringing vast hordes with him from the Euxine and Caspian regions and the northern parts of Asia. The Turk answers to this description, as many judge him to be the king of the north; his armies consist chiefly of cavalry, numerous in quantity and mighty in strength.
