John 7:28-29

²⁸Therefore Jesus cried in the temple teaching, and said, Ye know me, and ye know of whence I am; and I came not of myself, but he is true that sent me, whom ye know not.

²⁹I know him, and if I say that I know him not, I shall be like to you, a liar; but I know him, for of him I am, and he sent me.
