Jerome : (Verse 10) The fortified city will be deserted; the beautiful city will be abandoned and left like a wilderness. There the calf will graze, and there it will lie down and consume its branches. Their idols will be cut down like groves, and the flock that dwells far away will be left like a deserted flock, and it will be a long time in the pasture, and there the flocks will rest, and after a long time there will be no green in it, for it is dried up. Jerusalem, once a strong and fortified city, because it did not receive its masters but said: Come, let us kill him, for this is the heir and our inheritance (Matthew 21:38), will be deserted. And that which was once beautiful, of which it is said in Ezekiel: You ate fine flour, honey, and oil, and you became exceedingly beautiful (Ezek. 16:13), and in which dwells He of whom it is written: You are fairer than the sons of men (Ps. 45:3), will be left and abandoned like a desert, as the Lord says to the Apostles: Arise, let us go from here (John 14:31). There the calf, the Roman army, will graze, of which it is also said in another place under the name of boar: The boar from the forest will ravage it, and the singular wild beast has grazed on it (Ps. 80:14). And there he will lie down and consume its branches under the metaphor of a vine and its shoots, so that nothing green remains in it, nothing of the branches, but the enemy consumes everything. According to the Septuagint, because they did not receive a good shepherd: therefore they will be like a forsaken flock, and will be open to the bites of beasts; and nothing green will remain in them, because drought will possess everything. — Commentary on Isaiah
