Who art thou? - As Jesus did not expressly say in the previous verse that he was the Messiah, they professed still not to understand him. In great contempt, therefore, they asked him who he was. As if they had said, "Who art thou that undertakest to threaten us in this manner!" When we remember that they regarded him as a mere pretender from Galilee; that he was poor and without friends; and that he was persecuted by those in authority, we cannot but admire the patience with which all this was borne, and the coolness with which he answered them.

Even the same ... - What he had professed to them was that he was the light of the world; that he was the bread that came down from heaven; that he was sent by his Father, etc. From all this they might easily gather that he claimed to be the Messiah. He assumed no new character; he made no change in his professions; he is the same yesterday, today, and forever; and as he had once professed to be the light of the world, so, in the face of contempt, persecution, and death, he adhered to the profession.

The beginning - From his first discourse with them, or uniformly.

Who art thou? - This marks the indignation of the Pharisees - as if they had said: Who art thou that takest upon thee to deal out threatenings in this manner against us?

Jesus saith unto them, Even the same that I said unto you from the beginning - Rather, Just what I have already told you, i.e. that I am the light of the world - the Christ - the Savior of mankind. There are a variety of renderings for this verse among the critics. Some consider την αρχην (which makes the principal difficulty in the text) as the answer of our Lord. Who art thou? I am την αρχην, the chief, the supreme; and have therefore a right to judge, and to execute judgment. But if our Lord had intended to convey this meaning, he would doubtless have said ἡ Αρχη, or ὁ Αρχων, and not την αρχην, in the accusative case. This mode of reading appears to have been followed by the Vulgate, some copies of the Itala, and some of the fathers; but this construction can never be reconciled to the Greek text. Others take την αρχην as an adverb, in which sense it is repeatedly used by the best Greek writers; and, connecting the 25th with the 26th verse, they translate thus: I have indeed, as I Assure ye, many things to say of you, and to condemn in you. See Wakefield. Raphelius takes up the words nearly in the same way, and defends his mode of exposition with much critical learning; and to him I refer the reader. I have given it that meaning which I thought the most simple and plain, should any departure from our own version be thought necessary: both convey a good and consistent sense.

Then said they unto him, who art thou?.... That talks at this rate, and threatens with death, in case of unbelief; this they said with an haughty air, and in a scornful manner:

and Jesus saith unto them, even the same that I said unto you from the beginning; meaning, either of this discourse, as that he was the light of the world, and which he continued to assert; or of his being had before the sanhedrim, when he affirmed that God was his Father, and by many strong arguments proved his divine sonship; or of his ministry, when by miracles, as well as doctrines, he made it to appear that he was he that was to come, the true Messiah; or who spake from the beginning to Moses, saying, I am that I am, hath sent thee, and to the church, and Jewish fathers in the wilderness; and who is that word that was from the beginning with God; and who is called the beginning, the first cause of all things, and of the creation of God; and some think this is intended here.

Even the same that I said unto you from the beginning (τὴν ἀρχὴν ὅ τι καὶ λαλῶ ὑμῖν)

A very difficult passage, on which the commentators are almost hopelessly divided. There are two main classes of interpretations, according to one of which it is to be read interrogatively, and according to the other, affirmatively. The two principal representatives of the former class are Meyer, who renders "Do you ask that which all along (τὴν ἀρχὴν) I am even saying to you?" and Westcott, "How is it that I even speak to you at all (τὴν ἀρχὴν)"? So also Milligan and Moulton. This latter rendering requires the change of ὅ τι, the relative, that which, into the conjunction ὅτι, that.

The second class of interpreters, who construe the passage affirmatively, vary in their explanations of τὴν ἄρχην, which they render severally, altogether, essentially, first of all, in the beginning. There is also a third class, who take τὴν ἄρχην as a noun, and explain according to Revelation 21:6, "I am the beginning, that which I am even saying unto you." This view is represented mostly by the older commentators, Augustine, Bede, Lampe, and later by Wordsworth.

I adopt the view of Alford, who renders essentially, explaining by generally, or traced up to its principle (ἀρχὴ). Shading off from this are Godet, absolutely; Winer, throughout; Thayer, wholly or precisely. I render, I am essentially that which I even speak to you. If we accept the explanation of I am, in John 8:24, as a declaration of Jesus' absolute divine being, that thought prepares the way for this interpretation of His answer to the question, Who art thou? His words are the revelation of Himself. "He appeals to His own testimony as the adequate expression of His nature. They have only to fathom the series of statements He has made concerning Himself, and they will find therein a complete analysis of His mission and essence" (Godet).

{9} Then said they unto him, Who art thou? And Jesus saith unto them, Even {f} the same that I said unto you from the beginning.

(9) He will eventually know who Christ is who will diligently hear what Christ says.

(f) That is, I am Christ, and the Saviour, for so I told you from the beginning that I was.

8:25 Who art thou? No doubt asked with a sneer; hence, he only refers them to his past words.

8:25 Even what I say to you from the beginning - The same which I say to you, as it were in one discourse, with one even tenor from the time I first spake to you.

25. Who art thou?-hoping thus to extort an explicit answer; but they are disappointed.

8:21-29 Those that live in unbelief, are for ever undone, if they die in unbelief. The Jews belonged to this present evil world, but Jesus was of a heavenly and Divine nature, so that his doctrine, kingdom, and blessings, would not suit their taste. But the curse of the law is done away to all that submit to the grace of the gospel. Nothing but the doctrine of Christ's grace will be an argument powerful enough, and none but the Spirit of Christ's grace will be an agent powerful enough, to turn us from sin to God; and that Spirit is given, and that doctrine is given, to work upon those only who believe in Christ. Some say, Who is this Jesus? They allow him to have been a Prophet, an excellent Teacher, and even more than a creature; but cannot acknowledge him as over all, God blessed for evermore. Will not this suffice? Jesus here answers the question. Is this to honour him as the Father? Does this admit his being the Light of the world, and the Life of men, one with the Father? All shall know by their conversion, or in their condemnation, that he always spake and did what pleased the Father, even when he claimed the highest honours to himself.
