Isaiah 31:8Meaning & Commentary from the Church Fathers

They will turn away from all forms of unclean and impure idolatry, ceasing to serve the works of their hands, whether they be crafted of gold, silver, or any other valuable material. Before our Savior's arrival, humanity was overwhelmed by fear of such idols; some worshipped created beings, while others exalted the elements of the world that rightly belong to God. As the prophet states, “Of their silver, and of their gold, they made idols for themselves” (Hosea 8:4). Yet with the emergence of Christ, the entire world was liberated from these shameful and grievous sins. Temples, altars, and man-made idols were dismantled, and the deceit of Satan, which had tainted the earth, was cast aside. Therefore, as these human inventions are destroyed, Satan, the architect of this deception, will also meet his end. He will fall, not by human swords, but will be filled with dread as he joins other malevolent forces in the depths of hell. This is what the prophet highlights, asserting that the mighty and fierce rulers on earth will fall. In what manner will this transpire? They will be vanquished as if struck by stone, which signifies the unshakeable and indestructible might of the Savior. Embraced by Divine power, akin to a stone fortified as a barrier, the demons will yield to victory, and none will escape, as all who attempt to flee will be caught. Consequently, who among them will ultimately escape if they are enclosed like cattle within a stone stockade, with no means of escape? The power of the Savior has achieved this by abolishing Assyria, that is, Satan, and eradicating the evil forces aligned with him, encircling them as with a fortification, rendering them inactive and imprisoning them behind the gates of hell for eternal punishment.

If you do this, renouncing the idols of precious metal that have led you to sin and caused the fall of your city, then Assyria will experience the very fear that causes your flight, not through human swords or military power, but through the might of God. He commands the angel who annihilated one hundred and eighty-five thousand Assyrians in a single night. The king of Assyria himself will not flee from human weapons but will be consumed by God's wrath, leading to the downfall of his young warriors and the strong, who will find refuge among the Medians, of whom it is stated against Babylon, "Behold, I will stir up the Medians against you." The might of the Assyrians will vanish due to the fear of the Lord, and all their princes will be filled with dread. For the Lord has spoken and promised, and His word is as good as done. His fire in Zion and His furnace in Jerusalem will incinerate His enemies like straw and timber in a flame that emerges from Jerusalem. Some interpret the phrase, "In that day a man shall cast away his silver idols," as an assurance that after returning from Babylonian exile and leading up to Christ's coming, the children of Israel would cease idol worship. This passage also indicates that the Assyrian will not be defeated by an angel but by the Medians, whose ancient and once-mighty kingdom, having offended God, will be destroyed and subjugated by their conquerors. The Nazarenes understand this passage as a call to the children of Israel who have rejected the Son of God due to wicked intentions! Turn to Him and His apostles. If you do this, you will forsake all the idols that previously led you to sin, and the adversary will be vanquished, not by your strength, but through God's mercy: his young soldiers who once served him will be surrendered to the church, and all his power will diminish, while false philosophies and corrupt doctrines will flee. The Lord has decreed it shall be so—a fire or radiant light in Zion, and a furnace in Jerusalem. In Hebrew, the words for fire and light share the same letters—aleph, vav, and resh—where reading it as "ur" means fire, and as "or" indicates light. This is noted because while Simmachus uniquely translated it as fire, Aquila and Theodotion rendered it as light. The rendering by the Seventy mentioning the rock being enclosed as a trench, and defeat for those who that manage to escape, remains unclear to me. We can only assert that the young men of the Assyrian king, destined for defeat and captivity, will be encircled by the rock, which signifies the Lord's power enveloping them like a city surrounded by a trench. In regard to the subsequent blessing, "Blessed is he who has seed in Zion and family members in Jerusalem," we might deduce that this divine message urges those escaping to Egypt to return to Jerusalem and bear children. Such a person will be promised happiness and safeguarded by the Lord's aid. Elsewhere, it is declared, "The glory of this last house shall surpass that of the first" (Haggai 2), which can pertain to the Church—the vision of the world and the watchtower, about which it is said, "Glorious things are told of you, O city of God" (Psalm 87:3). Furthermore, it is stated, "The river brings joy to the city of God" (Psalm 46:4). For the divine fire acts as a crucible, consuming sinners and destroying their works—wood, hay, and stubble—or serves as a glorious light that epitomizes the righteousness of the faithful and the punishment of the unrighteous.
