Jerome : (Verse 26.) And her gates will mourn and lament, and the city itself, desolate, will sit upon the earth. Which we see with our own eyes until this day. The interpretation according to tropology is easy, that whoever gives a place to the devil and does not keep their heart guarded with all vigilance, let their gates mourn: and in the absence of the bridegroom, let them always be in mourning, and falling from the heights, let them sit in the dust of the earth. — Commentary on Isaiah
