John 8:52-59

The Jews said unto him, Now we know that thou hast a demon. Abraham died, and the prophets; and thou sayest, If a man keep my word, he shall never taste of death. Art thou greater than our father Abraham, who died? and the prophets died: whom makest thou thyself? Jesus answered, If I glorify myself, my glory is nothing: it is my Father that glorifieth me; of whom ye say, that he is your God; and ye have not known him: but I know him; and if I should say, I know him not, I shall be like unto you, a liar: but I know him, and keep his word. Your father Abraham rejoiced to see my day; and he saw it, and was glad. The Jews therefore said unto him, Thou art not yet fifty years old, and hast thou seen Abraham? Jesus said unto them, Verily, verily, I say unto you, Before Abraham was born, I am. They took up stones therefore to cast at him: but Jesus hid himself, and went out of the temple.
