Eusebius of Caesarea : By this it is clearly promised that the glory of Israel and all her riches will be taken away, and only a few, who like the few berries on an olive branch can be counted easily, will be left. These are the ones who believe in the Lord. Just after this there is a prophecy of the entire human race turning away from the error of idolatry and recognizing the God of Israel. — PROOF OF THE GOSPEL 2:3 Jerome : (Verse 4.) And it shall come to pass in that day, the glory of Jacob shall be diminished, and his fatness shall wither away. When, he says, Damascus is captured, and the city ceases to exist, and such glory crowns it, as crowns Israel, that is, the ten tribes: then all defense, and the fattest flesh, and refuge shall wither away from Jacob: for he will not have anything with which to devastate Jerusalem. We read above that Rezin, the king of Syria, and Pekah, the son of Remaliah, the king of Israel, went up to Jerusalem to fight against it: and it was announced to the house of David: Syria has rested upon Ephraim, of whom the Prophet speaks to Ahaz: Do not fear, and let not your heart be afraid of these two smoldering stumps, of these smoky tails, in the furious wrath of Rezin, the king of Syria, and the son of Remaliah, because he has plotted evil against you, both Syria, the worst enemy, Ephraim, and the son of Remaliah. — Commentary on Isaiah Jerome : (Verse 4) And in that day, the glory of Jacob shall fade, and the fat of his flesh shall waste away. After the remnants of Syria had been, just as once had been the glory of the sons of Israel, and their salvation had been given to the nations by their transgression, then all the glory of the Jews will be diminished, with which they were glorious in the entire world, and their plump flesh will waste away, lacking prophets, signs and wonders, the present help of God, and the dignity of the priesthood: but the whole body of their nation will wither away and be reduced to nothing. — Commentary on Isaiah
