John Chrysostom
The assumption is that this refers to the defeat of Gog and Magog; however, I believe the prophet is alluding to the final day of the world, as is evident in what follows.
Their slain shall be cast forth, and out of their carcasses shall rise a stink: the mountains shall be melted with their blood.
וְחַלְלֵיהֶ֣ם יֻשְׁלָ֔כוּ וּפִגְרֵיהֶ֖ם יַעֲלֶ֣ה בָאְשָׁ֑ם וְנָמַ֥סּוּ הָרִ֖ים מִדָּמָֽם׃
2 Church Fathers comment on this verse
The assumption is that this refers to the defeat of Gog and Magog; however, I believe the prophet is alluding to the final day of the world, as is evident in what follows.
Listen, you nations, and pay attention, you rulers: let the earth and its inhabitants, the cosmos and the people upon it, take heed. For the indignation of the Lord rests upon all tongues, and His wrath is directed towards their multitude, aimed at their destruction and surrender to slaughter. Their scourges will be overturned, and the stench of the dead will rise, while the mountains will be soaked with their blood. The celestial powers will be shaken, the sky will be rolled up like a scroll, and the stars will fall like leaves from a vine and from a fig tree. My sword will be sheathed in the heavens.
Having articulated clearly that the Jewish synagogue would face ruin and be handed over to those who pillage it for captivity and prey, and having linked this with the calling of the Gentiles—for many who are weak will face captivity—he now delivers a crucial message for those who once held a temple mindset but have learned to walk justly through faith in Christ. He addresses the impending judgment that awaits all, both the humble and the great. Thus, he calls to the Gentiles, as if they were distant: “Listen, you nations, and pay attention, you rulers.” Yet he truly meant to invite them closer. While they dwell in error, worshipping creation instead of the Creator, they remain distant from God. However, once the reasons for their estrangement are removed, they become God’s own and are regarded as near, having shared in Him through the communion of the Holy Spirit. Therefore, he urges the Gentiles and rulers to approach; let the earth and its residents, the cosmos and its people, also listen. What is being unveiled here? He indicates that the wrath threatens all who dwell on the earth—not indiscriminately, but specifically those who have not turned from sin and carry the stain of moral impurity within their souls. The overall message conveys that they shall meet their demise and face destruction, contaminating every place as if they were decaying corpses. The mountains, it is said, will be drenched in their blood. Following this, to clarify the timing, he places within his discourse the prophecy about the end of the world, stating that the sky will be rolled up like a scroll and the stars will fall like foliage, mirroring the words of the Savior’s disciple regarding the last day, when the heavens will vanish with a great noise, the elements will be consumed, and both the earth and its deeds will be destroyed; yet we will receive new heavens and a new earth in accordance with His promises (2 Pet. 3:10, 13). Thus, the alignment of the heavens and the falling of the stars may signify the renewal of creation. And the Divine Paul declared that creation will be liberated from decay into the glorious freedom of the children of God (Rom. 8:21).
