{And I am not come of myself} (kai ap' emautou ouk
el(886c)utha). Kai here="and yet." Jesus repeats the claim of
verse  17  and also in  5:30  8:28  12:49  14:10 . {Whom ye know
not} (hon humeis ouk oidate). Jesus passes by a controversy
over the piece of popular theology to point out their ignorance
of God the Father who sent him. He tersely agrees that they know
something of him. Jesus says of these Jews that they know not God
as in  8:19,55 .
