Expositor's Bible Commentary Commentary John 8:18

"I am he that beareth witness of myself, and the Father that sent me beareth witness of me." — John 8:18 (ASV)

Jesus argued further that the Pharisees were not qualified to render a verdict on the validity of his witness because they were using the wrong criterion of “human standards.” He, on the other hand, is not measurable by such standards. He appealed to the rule of the OT law that prescribed two witnesses for an acceptable proposition . He would be qualified as one of the witnesses (for no human witness can authenticate a divine origin) and his Father, who sent him, as the other (cf. 5:23–21, 37).
