John Gill Commentary John 8:15

"Ye judge after the flesh; I judge no man." — John 8:15 (ASV)

Ye judge after the flesh
According to their carnal affections and prejudices; taking the Messiah to be a temporal prince, and his kingdom to be of this world, they judged that Jesus could not be he; they looked upon him as a mere man, and seeing him in much outward meanness, in his human nature, they judged of him according to this outward appearance: or "you" that are "after the flesh" judge; to which sense the Persic version agrees, "for you are carnal"; and so judged as carnal men, who are very improper persons to judge of spiritual things:

I judge no man ;
according to the sight of the eyes, or the hearing of the ears: Christ did not take upon him to judge and determine in civil affairs, or in things pertaining to a court of judicature among men; this was not his province; an instance of this there is in the context, in not condemning the woman brought to him; nor did he judge the persons and states of men, or proceed to pass any sentence of condemnation on them; he came not to condemn, but save the world; this was not his business now; otherwise, all judgment is committed to him, and which he will exercise another day.
