Isaiah 5:29Meaning & Commentary from the Church Fathers

In that day, He will cry out on their behalf as the tumult of the sea rises, and they will gaze upon the earth, only to find darkness that is grim amidst their confusion.

The consequences of the righteous Judge’s wrath against them will not be limited to this alone but will become evident through what follows. Although these unfortunate souls endured great desolation, faced the agonies of hunger and thirst, and weathered the tribulations of war, they remained estranged from God, thus under His anger. This is reflected in the saying that His hand remains lifted high, as it does for those who have sinned, for the striking hand is always raised. What then will the bitterness be for the mountains, those who will execute this wrath with an unusual ferocity and boldness? This is clarified further, for it is declared He will establish a sign in the languages of those who are distant. The ones who ravaged Judah and burned Jerusalem, along with its cities, did not come from close by but gathered from far-off lands across the earth.

The sign will be presented as if in the context of warfare; it is customary for generals to raise banners high to mobilize their troops. The prophet Isaiah notes this, saying, “He will be seized like a flag on the mountain, and like a banner on the hills” (Isaiah 30:17). Those who raise banners on elevated ground either position them upright, tilt them, or hang something from them, which serves as a guide for the fighting force. This way, the army discerns the commander’s desires. Similarly, the passage suggests a signal will be raised to attract them. This notion also draws from the habits of beekeepers, who whistle to lead bees from their hives to the flowers and later gather them back. So it will be, as they swiftly come, almost as effortlessly as birds, unconcerned by hunger, unafraid of toil, and never resting, fully equipped for battle.

With indomitable steeds, they will charge like a storm, fierce as lions, and consuming as beasts; they will be overwhelmingly potent, able to conquer without engaging in combat, for no one will be able to withstand them or gather sufficient assistance against them. At that time, there will be lamentations mingled with cries, creating a sound reminiscent of the sea surging over the land of Judah. A harsh darkness will also prevail, not a mere night or fog, but one borne of fear and confusion, for severe calamities cloud the mind. Thus, the God of all creation does not act without purpose; His foresight into the future and His detailed warnings about impending calamities serve to awaken us. For when we become deaf to His calls for repentance and dismiss the words urging us to turn back to Him, He seeks to instill within us a healthy fear of falling into such devastating punishments, prompting us to turn from evil and, at last, direct our hearts toward righteousness.

I have encountered an interpretation suggesting that the phrase, 'He shall lift up a banner to the nations from afar, and whistle it from the ends of the earth,' relates to the calling of the Gentiles; for when the banner of the Cross was raised, and the weight of sin was laid aside, they swiftly came and believed. However, I am uncertain how the subsequent verses align with this understanding.
