39:1-10 The Lord will make the most careless and hardened transgressors know his holy name, either by his righteous anger, or by the riches of his mercy and grace. The weapons formed against Zion shall not prosper. Though this prophecy is to be fulfilled in the latter days, it is certain. From the language used, it seems that the army of Gog will be destroyed by miracle.Thou shalt fall upon the open field,.... Some part of his army should fall upon the mountains, and others upon the plain; wherever they will be found, they will be destroyed, either by the sword of the Jews and Christian princes, or by God's judgments from heaven:

for I have spoken it, saith the Lord God; and therefore it should surely come to pass, since no word of his ever fails; this is added to assure of the truth of it, since it might be thought incredible that so large an army should be destroyed.
