John 8:15

12 Again therefore Jesus spake unto them, saying, I am the light of the world: he that followeth me shall not walk in the darkness, but shall have the light of life.

13 The Pharisees therefore said unto him, Thou bearest witness of thyself; thy witness is not true.

14 Jesus answered and said unto them, Even if I bear witness of myself, my witness is true; for I know whence I came, and whither I go; but ye know not whence I come, or whither I go.

15 Ye judge after the flesh; I judge no man.

16 Yea and if I judge, my judgment is true; for I am not alone, but I and the Father that sent me.

17 Yea and in your law it is written, that the witness of two men is true.

18 I am he that beareth witness of myself, and the Father that sent me beareth witness of me.
