John 8:52-57

⁵²The Jews said to him, Now we know that thou hast a demon. Abraham died, and the prophets; and thou sayest, If any one keep my word, he will never taste of death.

⁵³Art thou greater than our father Abraham, who died? The prophets also died. Whom dost thou make thyself?

⁵⁴Jesus answered, If I glorify myself, my glory is nothing. It is my Father that glorifieth me, of whom ye say, He is our God:

⁵⁵yet ye know him not; but I know him. And if I should say, I know him not, I should be a liar like you. But I know him, and keep his word.

⁵⁶Your father Abraham exulted that he might see my day; and he saw it, and was glad.

⁵⁷The Jews therefore said to him, Thou art not yet fifty years old, and hast thou seen Abraham?
