John 8:26

I have many things to say and to judge of you - Or, to speak and to condemn, etc. I could speedily expose all your iniquities - your pride and ambition, your hypocrisy and irreligion, your hatred to the light, and your malice against the truth, together with the present obstinate unbelief of your hearts, and show that these are the reasons why I say you will die in your sins; but these will appear in their true light: when, after you have crucified me, the judgments of God shall descend upon and consume you.

He that sent me is true - Whatever he hath spoken of you by the prophets shall surely come to pass; his word cannot fail.

I have many things to say - There are many things which I might say to reprove and expose your pride and hypocrisy. By this he implied that he understood well their character, and that he was able to expose it. This, indeed, he had shown them in his conversations with them.

And to judge of you - To reprove in you. There are many things in you which I might condemn.

But he that sent we is true - Is worthy to be believed, and his declarations about men are to be credited. The meaning of this verse may be thus expressed: "I have indeed many things to say blaming or condemning you. I have already said many such things, and there are many more that I might say; but I speak only those things which God has commanded. I speak not of myself I come to execute his commission, and he is worthy to be heard and feared. Let it not be thought, therefore, that my judgment is rash or harsh. It is such as is commanded by God."

8:26 I have many things to say and to judge of you - I have much to say concerning your inexcusable unbelief: but he that sent me is true - Whether ye believe or no. And I speak the things which I have heard from him - I deliver truly what he hath given me in charge.
