Jerome : (Verse 4) And the doorposts of the cardinal's palace were shaken by the voice of the one who cried out, and the house was filled with smoke. The seraphim cried out, and throughout the whole earth they proclaimed the mystery of the Trinity, when the entire earth learned of the passion of the Lord and Savior. Immediately, the threshold of the Temple was either raised or lifted up, and all its hinges fell down, fulfilling the Savior's threat, saying: Your house will be left to you desolate (Matthew 23:38). And what a beautiful arrangement of words. After the earth is filled with the glory of the Lord of hosts, the Temple of the Jews is filled with the darkness of ignorance, and with darkness, and with smoke, which is harmful to the eyes. Or certainly through the smoke of the Temple the fire is revealed. For first the Gospel of the Savior was preached throughout the whole world, and after forty-two years from the Lord's passion, Jerusalem was captured, and the Temple was set on fire. The Jews believe that the Temple was filled with smoke, which signifies incense, and through this the coming of the divine majesty. — Commentary on Isaiah
