John 8:53-59

53 Art thou greater than our father Abraham who is dead? And the prophets are dead. Whom dost thou make thyself?
54 Jesus answered: If I glorify myself, my glory is nothing. It is my Father that glorifieth me, of whom you say that he is your God.
55 And you have not known him: but I know him. And if I shall say that I know him not, I shall be like to you, a liar. But I do know him and do keep his word.
56 Abraham your father rejoiced that he might see my day: he saw it and was glad.
57 The Jews therefore said to him: Thou art not yet fifty years old. And hast thou seen Abraham?
58 Jesus said to them: Amen, amen, I say to you, before Abraham was made, I AM.
59 They took up stones therefore to cast at him. But Jesus hid himself and went out of the temple.
