John 8:15

Verse 15. You judge, and also bear testimony concerning other men, according to the flesh, and according to outward shew and appearances only. I judge no one in this manner. And whatever judgment I pass, or if I give testimony, my testimony is true, as coming also from the Father, with whom I am one in nature, though a distinct person: and two, according to the law, are enough to give evidence. Witham.—You judge according to the flesh, and so forth Because you do not understand the ways of God, and think you only see in me the person of man; therefore I seem to you to be arrogant, bearing witness of myself. Man indeed, who wishes alone to bear testimony of himself, is arrogant, and not to be believed, because all men are frail and liable to be deceived; but light and truth itself can neither deceive nor be deceived.
