Eusebius of Caesarea : He promises those crying out and who give unceasing praise to the Lord, "While you are still speaking, behold, I am here." … Now to those who will be worthy of the new age and involved in the things the Lord promises, he will no longer give their fruit to their enemies, but they will profit from these themselves. For they are correcting their lives in the direction of virtue and in godly manner are pursuing righteousness and enjoying their own harvest. — COMMENTARY ON Isaiah 2:52 Jerome : (Vers. 8, 9.) The Lord has sworn by his right hand and by the strength of his arm: If I give your wheat beyond food to your enemies, and if the sons of aliens drink your wine, in which you have labored: for those who gather it will eat it and praise the Lord, and those who carry it will drink it in my holy courts. LXX: The Lord has sworn by his right hand and by the strength of his arm: If I give my wheat beyond food to your enemies, and if the sons of aliens drink your wine, in which you have labored: but those who gather it will eat it and praise the Lord, and those who gather it will drink it in my holy courts. Almighty God, who said to the Church, 'I have set watchmen on your walls who shall never hold their peace day nor night. You who make mention of the Lord, do not keep silent, and give Him no rest till He establishes and till He makes Jerusalem a praise in the earth.' Now He swears by His right hand and by the arm of His strength. Concerning whom we frequently say that He is our Lord and Savior, who, according to the Apostle, is the power of God and the wisdom of God (1 Corinthians 1). He swears that the grain and wine of Jerusalem shall never be given as food to the enemies, nor shall aliens devour the labor of it; but those who sow in tears shall reap in joy, and those who reap, with joyful shouting, and with the chaff removed, they shall gather the pure grain into the barns. They themselves shall eat the labor of their hands, and shall lift up the Lord with eternal praise, and shall drink wine in His holy courts. Because either we understand many dwellings with the Father, if we accept them as the future blessedness in the kingdom of heaven, or certainly the Churches divided throughout the whole world, in which we are planted, and afterwards we will flourish in the house of the Lord. But when He says: I will no longer give your wheat to your enemies, and foreigners will not drink your wine, in which you have labored, He shows the previous labor of the Jews, and that all their works were possessed by demons when they were wavering between God and idols, when Elijah said to them: How long will you limp with both feet? if the Lord is God, follow him (III Kings XVIII, 21). And according to the typical history narrated in the book of Judges, the Midianites came and devastated their crops as far as Gaza, so that the food of men was turned into fodder for animals (Judges VI). This is the wheat and this is the wine that they will not eat unless they praise the Lord, and they will not drink unless in his holy courts, of which the Lord said during his passion: Amen, amen I say to you, I will not drink from the fruit of this vine until I drink it new in the kingdom of my Father (Mark XIV, 25). Which part of the Church is fulfilled when the Lord says to His disciples: Drink, my friends, and be intoxicated, my brothers, for wine gladdens the human heart (Psalms 104). And it is drunk in broad daylight by Joseph and his brothers (Genesis 44). And it will be fulfilled more fully when the earth is intoxicated with the blessings of the Lord. The wheat from which the heavenly bread is made, that is what the Lord speaks of: My flesh is truly food. And again regarding wine: And my blood truly is drink (John VI). — Commentary on Isaiah Theodoret of Cyrus : As you battle courageously, I will lead from the front. Since there is no one else better by whom one should swear, then by my own glory and by my own power I swear, since I will guard your harvest for you and stop those who are perpetual thieves, while you will profit from your own labors. Wheat and wine and food, spiritually speaking, signify the harvest of righteousness. — COMMENTARY ON Isaiah 19:62.8-9
