{I have many things to speak and to judge concerning you}
(polla ech(9320)peri hum(936e) 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  16 ). Whatever they think of Jesus the Father who
sent him is true (al(8874)h(8873)). They cannot evade responsibility
for the message heard. So Jesus goes on speaking it from the
Father.
