Isaiah 66:6Meaning & Commentary from the Church Fathers

When he proclaimed, I will choose their offenses, and their sins I will repay them, he clearly indicated the realization of the warnings given. As though their adversaries had already besieged their city and temple, a voice echoed from the city, and a voice from the temple, for the priests wept in unison, and all the people mourned collectively. It was entirely understandable for them to lament and grieve in the wake of the calamity of war, as there was no escape from the impending evil.

A cry rises from the city, for it is besieged by adversaries; a lament echoes from the temple, whether from the priests praying or from the citizens who, overwhelmed by their foes, have sought sanctuary there. It is the voice of the Lord delivering justice to those who oppose Him, repaying the unrighteous Jews and Gentiles who had the audacity to assail them prior to the incursion of the tribe of Gog.

The clamoring voices from the city and the temple express the Lord's judgment upon His adversaries. The Septuagint replaces "noise" with "cry," yet the essence remains unchanged. We seek to understand the disgrace of the Jewish people, who proclaimed, "Let the Lord demonstrate His glory, so we may witness Your joy, not through vain promises but with our own eyes behold the victory of our Sovereign." The voice of the Lord calls out from the city, clearly indicating Jerusalem, besieged by the Roman forces and internally fragmented due to rebellion, which led them to divide into three factions: one occupying the temple and holding sacred places while battling both the external enemy and their fellow countrymen.
