John 8:13 - Ellicott's Commentary On The Whole Bible

Thou bearest record of thyself; thy record is not true. — Better, Thou bearest witness of Thyself; Thy witness is not true. (Comp. Note on John 5:31.) The Authorised version here, by a change of word, renders the connection less obvious than it really is. The Pharisees, standing probably in the front of the crowd listening to Him, bring a technical objection to His statement, and one which He had Himself admitted the force of. “According to your own words,” they mean, “what you now say is not valid.” They stand in the light of day, but demand a formal proof that the Sun has risen.
