Isaiah 52:2

The creation, then, after being restored to a better and more fitting state, remains, rejoicing and exulting over the children of God at the resurrection. For their sake the creation now groans and travails, waiting itself also for our redemption from the corruption of the body, that, when we have risen and shaken off the mortality of the flesh, according to that which is written, "shake off the dust, and arise and sit down, O Jerusalem," and have been set free from sin, it also shall be freed from corruption and be subject no longer to vanity but to righteousness.

(Verse 2, 3.) Shake off the dust; arise, Jerusalem! Loose the bonds of your neck, captive daughter Zion. For thus says the Lord: You were sold for nothing, and you shall be redeemed without money. LXX: Shake off the dust; arise, Jerusalem! Loose the bonds of your neck, captive daughter Zion. For thus says the Lord: You were sold for nothing, and you shall be redeemed without money. By no means does the word of the Prophet refer to Jerusalem, that is, to the ruins of its stones, and to the ashes and cinders, but it refers to the people who dwell within it. And it is called the daughter, because of the weakness of its spirit, as the following verse shows, in which it says: Loose the bonds of your neck, captive daughter Zion. Truly, the people of Judah are captives, who still bear the yoke of Nebuchadnezzar to this day, and are bound by the ropes of their sins and blasphemies. They were sold for nothing, and have done nothing deserving of redemption. As it is said above: 'Behold, you were sold for your sins, and I have dismissed your mother because of your iniquities.' And it gives the reasons why they were sold, why they were rejected. For, he says, I came and there was no man; I called and there was no one who would listen. From which it is clear that they were handed over to error and demons because they had not heard the one shouting: Come to me, all you who labor and are burdened (Matthew 11:28). But those who want to believe will be redeemed, not with silver and money, but with the precious blood of Christ, so that they may hear through the apostles: Grace to you and peace (Romans 1:7). For we are reconciled to God, not by merits, but by grace and faith in Christ. It is also said of the soul, which, defiled by the filth of vices, had lost the brightness of its former conduct, that it shakes off the dust with the Apostles, who clung to His feet (Matthew 10). For it could not be that the soul, which had submitted its neck to those passing by and had mingled with the earth, saying, 'My soul is humbled even to the dust, my belly has adhered to the earth' (Psalm 43:25), should receive the likeness of the earth. From which the Apostle calls us back, saying: As we have borne the image of the earthly, let us also bear the image of the heavenly (I Cor. XV, 49). Therefore those who are in the flesh cannot please God (Rom. VIII). Not that the nature of the flesh is…
