John 8:23 (KJV)

I am one that bear witness of myself, and the Father that sent me beareth witness of me.

Then said they unto him, Where is thy Father? Jesus answered, Ye neither know me, nor my Father: if ye had known me, ye should have known my Father also.

These words spake Jesus in the treasury, as he taught in the temple: and no man laid hands on him; for his hour was not yet come.

Then said Jesus again unto them, I go my way, and ye shall seek me, and shall die in your sins: whither I go, ye cannot come.

Then said the Jews, Will he kill himself? because he saith, Whither I go, ye cannot come.

I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.

Then said they unto him, Who art thou? And Jesus saith unto them, Even the same that I said unto you from the beginning.

I have many things to say and to judge of you: but he that sent me is true; and I speak to the world those things which I have heard of him.

They understood not that he spake to them of the Father.

Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.
