John 8:16-18

And yet if I judge,— At the same time our Lord told them, that if he should condemn any person for unbelief, such condemnation would be just, because his divine mission was true; being confirmed, not by his own testimony only, but by the Father's also; and because every sentence of that kind which he should pass, would be pronounced by the authority, and agreeably to the will of his Father. "Yet if I judge, my judgment is true, that is, just and equitable; for I am not alone; nor do I expect that you should believe me solely on my own testimony, but me, and the Father that sent me concurring in the same testimony." This led him to speak of the testimony which the Father bare to his divine mission. It is also written in your law, that the testimony of two men is true; "you could not justly complain, if I should punish you for your unbelief in such a case as this, since your own law directs you to believe every matter confirmed by the concurrent testimony of two witnesses, as my divine mission evidently is; for I am one that bear witness of myself, John 8:18 not by words only, but by all the actions of my life, which are perfectly agreeable to the character of the Messiah; and the Father that sent me beareth witness of me; that is, by the voice of his prophets, and by a voice from heaven; as well as by other means."
