John 7:27 YLT

²⁵  Certain, therefore, of the Jerusalemites said, 'Is not this he whom they are seeking to kill?

²⁶  and, lo, he doth speak freely, and they say nothing to him; did the rulers at all know truly that this is truly the Christ?

²⁷  but this one -- we have known whence he is; and the Christ, when he doth come, no one doth know whence he is.'

²⁸  Jesus cried, therefore, in the temple, teaching and saying, 'Ye have both known me, and ye have known whence I am; and I have not come of myself, but He who sent me is true, whom ye have not known;

²⁹  and I have known Him, because I am from Him, and He did send me.'
