I have many things to speak and to judge concerning you (polla ecw peri umwn lalein kai krinein). Instead of further talk about his own claims (already plain enough) Jesus turns to speak and to judge concerning them and their attitude towards him (cf. verse Genesis 16 ). Whatever they think of Jesus the Father who sent him is true (alhqh). They cannot evade responsibility for the message heard. So Jesus goes on speaking it from the Father.
