Jerome : (Verse 17) On that day the Lord will take away the ornament of the shoes. On which day? The Jews believe it to be the captivity of Babylon. We are more convinced that it is when they were captured by the Romans and lost all their clothing, gems, gold, jewelry, and various furnishings. Or, by the metaphor of women, it is said that all the adornment of cities was destroyed. Understand the ornaments of cities in the streets and porticoes, in the marketplace and gymnasiums, and in public walls. But if we consider this in relation to the state of souls, let us remember that when he is going to eat the flesh of the lamb and celebrate the Passover, his feet are shod, and as we pass through the wilderness, neither clothes nor shoes are consumed. What are these shoes? Those of which the Apostle writes to the Ephesians: Shod your feet in preparation for the Gospel of peace (Eph. 6:15). These are the shoes of souls that are destined to be lost when they walk with their necks extended and drag their clothes with their feet, and instead of the cleanliness of a matron, they sweep the filth of the earth. — Commentary on Isaiah
