(41) These things said Esaias, when he saw his glory.--The better text is, . . . because he saw His glory. (Comp. Note on the reading in John 12:17.) The result of seeing His glory was that he spake of Him. This is St. John's interpretation of the prophecy. Isaiah himself tells us, "I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple" (John 6:1). But no man hath seen God at any time. The Word is the express image of His Person. This glory was of the pre-incarnate Word, who was in the beginning with God, and was God.

Verse 41. - These things said Isaiah, because he saw his glory, and he spake of him. By this reference to the theophany of Isaiah 6:1, 2 the evangelist here identifies Christ with the Adonai whom the prophet saw in his vision, and thus expresses his conception of the Christ (comp. 1 Corinthians 10:4; Philippians 2:6). Because the prophet saw the glory of Christ, the unutterable majesty of the "Word of God," he delivered, as we know, this tremendous burden. Few utterances of the New Testament convey in more startling form the conviction of the apostles touching the pre-existence of the Lord, and the identification of the Divine Personality of the Christ, with the highest conception that the Hebrew prophet entertained of the Almighty One, of the eternal Godhead.

12:37-43 Observe the method of conversion implied here. Sinners are brought to see the reality of Divine things, and to have some knowledge of them. To be converted, and truly turned from sin to Christ, as their Happiness and Portion. God will heal them, will justify and sanctify them; will pardon their sins, which are as bleeding wounds, and mortify their corruptions, which are as lurking diseases. See the power of the world in smothering convictions, from regard to the applause or censure of men. Love of the praise of men, as a by-end in that which is good, will make a man a hypocrite when religion is in fashion, and credit is to be got by it; and love of the praise of men, as a base principle in that which is evil, will make a man an apostate, when religion is in disgrace, and credit is to be lost for it.These things said Esaias,.... Concerning the blinding and hardening of the Jews:

when he saw his glory, and spake of him; when he saw, in a visionary way, the glory of the Messiah in the temple, and the angels covering their faces with their wings at the sight of him; and when he spake of him as the King, the Lord of hosts, whom he had seen, Isaiah 6:1, from whence it is clear that he had respect to the Jews in the times of the Messiah. The prophet says in Isaiah 6:1 that he "saw the Lord": the Targumist renders it, "I saw", , "the glory of Jehovah"; and in Isaiah 6:5 he says, "mine eyes have seen the King", Jehovah, Zebaot, the Lord of hosts; which the Chaldee paraphrase renders, "mine eyes have seen", , "the glory" of the Shekinah, the King of the world, the Lord of hosts. Agreeably to which our Lord says here, that he saw his glory, the glory of his majesty, the glory of his divine nature, the train of his divine perfections, filling the temple of the human nature; and he spoke of him as the true Jehovah, the Lord of hosts; and which therefore is a very clear and strong proof of the proper divinity of Christ. And it may be observed from hence, that such persons who have a true, spiritual, and saving sight of Christ, of the glory of his person, and the fulness of his grace, cannot but be speaking of him to others, either in private, or in public, as Isaiah here did, and as the church in Sol 5:10; and as the apostles of Christ, John 1:1; and indeed, should they hold their peace, the stones would cry out; such must, and will speak of his glory in his temple, Psalm 29:9.
