John Calvin on Isaiah 32:14

14. For the palace shall be forsaken. Here also he describes more fully the desolation of the country; for, having mentioned in the former verse magnificent houses, he now likewise adds palaces and cities, so as to shew that there is nothing, however splendid and illustrious, that is exempted from that calamity. We see that men are dazzled by their own splendor, till they lift up their eyes to heaven; and the consequence is, that they are soothed to sleep in the midst of their wealth, and dread nothing. He therefore declares that all that was splendid, magnificent, and lofty, in Judea, cities, palaces, bulwarks, fortresses, all will be brought to nothing. When he says for ever, he again gives warning, as he formerly did, that this calamity will not last only for a single day, but that, as they had been long hardened in their vices, so it will be of long duration; for, if they had been punished only for a short time, being obstinate and intractable, they would quickly have relapsed into their natural disposition.
