17 Cry yet, saying, Thus saith the LORD of hosts; My cities through prosperity shall yet be spread abroad; and the LORD shall yet comfort Zion, and shall yet choose Jerusalem.
(Verse 17.) Still cry out, saying: Thus says the Lord of hosts: My cities shall still overflow with goods, and the Lord shall still comfort Zion, and shall still choose Jerusalem. LXX: And the angel who spoke in me said: Still cry out, saying: Thus says the Lord Almighty: Still cities shall be spread with goods, and the Lord shall still have mercy on Zion, and shall still choose Jerusalem. The angel who had spoken above to the prophet said: Cry out: Thus says the Lord of hosts, now he also urges him to cry out, not with the intensity of his voice, but with the intensity of his mind: and this is what he commands to be cried out: My cities shall still overflow with goods, which you now see devastated by the fire of the Babylonians, they shall again abound with all things, and the Lord shall comfort the present miseries with future goods, and shall choose Jerusalem, which he had recently cast away. But if we refer to the Church, to which true and eternal goods are promised, those goods must be believed, about which we read: See the good things of Jerusalem (Ps. 127:5). And in another place: If you are willing and obedient, you will eat the good things of the land (Isa. 1:19). And that: Trust in the Lord, and He will exalt you to possess the good things of the earth. Which a wise man, to whom the Lord had revealed the uncertain and obscure things of His wisdom, promises to himself with hope for the future, and says: I believe I shall see the good things of the Lord in the land of the living (Ps. 26:13). After the fires of the most savage persecution which the Church of the Lord endured from both the pagans and the heretical Arians, peace being restored, we see the Churches of the Lord flourish, and Zion consoled, and Jerusalem chosen, which it had previously rejected. We can understand this to refer to the temple of the Lord and to each and every believer. Some interpret the consoled Zion and chosen Jerusalem, and the other things that are preached in this manner by all the prophets, as referring to the heavenly Jerusalem, which, having been destroyed through ruin, is to be restored through virtues. We will interpret all these things more correctly about the Church.
