Isaiah 52:9

Israel was destroyed in the war with the Romans, so that very few survived to remain, and the holy city was deserted. But its desert places will rejoice, so it says. For the houses were mournful and filled with dejection for not having inhabitants. But they rejoice as if they have many living there. From the historical sense we can draw something that the spiritual senses can grasp. The church from the nations—that is, those believers from the nations who are called Zion and even Jerusalem—were few in the early days and the holy city of God, the church, was truly like a desert.

(Verse 9, 10.) Rejoice and praise together, O deserted Jerusalem, for the Lord has comforted his people; he has redeemed Jerusalem. The Lord has prepared his holy arm in the sight of all the nations; and all the ends of the earth shall see the salvation of our God. LXX: Let the deserted Jerusalem burst into joy together, for the Lord has had mercy on her, and has redeemed Jerusalem. The Lord will reveal his holy arm in the sight of all the nations. And all the ends of the earth shall see the salvation of our God. After the people of Judah were led into captivity and the city was burned, there were few or no inhabitants in Jerusalem. But when the one who spoke through the prophets and was with God in the beginning, the Word of God, dwelt amongst us and became flesh, the deserts of Jerusalem were restored. And he came, of whom it is written: 'He will build my city and bring back the captivity of my people, so that it shall never again be lamented by Jeremiah: How lonely sits the city that was full of people: she has become like a widow who was multiplied among the nations' (Lamentations 1:1). But let David hear the one singing, 'When the Lord restored the captivity of Zion, we became like those who are comforted' (Psalm 126:1, 4). And after a little while: We became joyful. And so that we know that these things are said not about the Jewish people, but about all who will believe in the Lord through the apostles, he sets forth and says: He who comforted her, or had mercy on her, and he who rescued or redeemed her, he himself has prepared or revealed his holy arm, in the sight of all nations: and all the ends of the earth shall see the salvation of our God. From which it is clear that, after the spiritual Jerusalem, that is, the Church, which was abandoned by the Jews, has been built by the Apostles, the arm of the Lord is revealed to all nations, and all the ends of the earth see his salvation. Which is understood in two ways. Either the Father reveals his arm to all nations, or the Son reveals his strength. Concerning which it is written: For power went out from him and healed all (Luke 6:19). And again: I perceived that power had gone out from me, which healed the woman with an issue of blood (Mark 5:30). But that the Son of God is called the right hand and arm of the Father, there are many testimonies, of which we will mention a few: His right hand and holy…
