John 8:14-18

14Jesus answered and said to them, Even if I bear witness concerning myself, my witness is true, because I know whence I came and whither I go: but ye know not whence I come and whither I go.

15Ye judge according to the flesh, I judge no one.

16And if also I judge, my judgment is true, because I am not alone, but I and the Father who has sent me.

17And in your law too it is written that the testimony of two men is true:

18I am [one] who bear witness concerning myself, and the Father who has sent me bears witness concerning me.
