John 8:25-27 - Joseph Benson’s Commentary on the Old and New Testaments

Then said they, Who art thou? This question they ask in derision, and not with any desire to be instructed. And Jesus saith, Even the same that I said unto you from the beginning Namely, of my public ministry, or from the time I first spake to you. Or, as Whitby renders it, I am what I before told you I was; a sense of the expression, την αρχην, (here rendered, from the beginning,) which he justifies by several passages of the Septuagint, particularly Genesis 13:4; Genesis 41:21; Genesis 42:18; Genesis 42:20; that is, I am one sent of God to reveal his will to you. I have many things to say and to judge of you That is, you say and judge many things of me, which from my words and deeds will appear to be false; but I have many things to say of you, what you are as to your spirit and conduct, and what you will be through the just judgment of God, which, though you will not believe, will be found true; for he that sent me to say them is true, and I speak those things which I have heard of him I deliver truly what he hath given me in charge, and he will finally verify my words. They understood not So exceeding stupid were they, and so blinded by the prejudices of their minds; that he spake to them of the Father Of God, as the person who sent him.
