Jerome : (Verse 17) And the lambs will be fed in their order: and the deserted places will be turned into abundance, and strangers will feast upon them. Instead of the lambs being fed in their order, which is understood in a positive sense, I do not know what the LXX, desiring something else, translated as 'they will be fed as plundered bulls'; understanding lambs as bulls, and again interpreting strangers as lambs. But when the Lord is exalted in judgment, and sanctified in His righteousness, so that the evil farmers may be destroyed, and the lofty cedar may be cut down by the axe of the Lord; then those who are among the number of lambs, not of goats, will be fed in the meadows of the Church, and will say: 'The Lord feeds me, and I lack nothing' (Psalms 23:1); and the people of the nations will eat the deserted things of the Jews, turned into abundance. This is according to the tropology. Moreover, to complete the order of the narrative, the same thing is said in other words, which we have read above: Your land is devoured by strangers in your presence, and it is deserted and destroyed by foreign peoples (Isaiah 1:7). For the multitude of nations gathered from the whole world dwell in Judea, and the previous peoples being expelled, therefore blindness has happened to the house of Israel, so that the fullness of the Gentiles may enter (Romans 11). Beautifully, according to the LXX, they were plundered and devastated and led into captivity like bulls, of whom the Lord had said: Fat bulls have surrounded me, so that the lambs may occupy the places of the bulls. — Commentary on Isaiah
