The evangelist saith, that these things Esaias said, when he saw his glory, and spake of him. Isaiah's sight of God's glory is described, Isaiah 6:1, I saw the Lord sitting upon a throne, high and lifted up, &c. The evangelist expounds this of Christ, which is an evident proof of the Deity of Christ, that he is Jehovah; for it was Jehovah whom the prophet there saw: and that the revelation of that dreadful wrath of God, did not only concern that particular age in which Isaiah lived, but the successive generation of the Jews, whom the prophet saw by the eye of prophecy would tread in the same steps, and use Christ (the Heir) as their forefathers had used him, and the prophets of that age.
