John 8:12 (KJV)

So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.

And again he stooped down, and wrote on the ground.

And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.

When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee?

She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.

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

Jesus answered and said unto them, Though I bear record of myself, yet my record is true: for I know whence I came, and whither I go; but ye cannot tell whence I come, and whither I go.

Ye judge after the flesh; I judge no man.

And yet if I judge, my judgment is true: for I am not alone, but I and the Father that sent me.

It is also written in your law, that the testimony of two men is true.
