John 8:51-59 New Revised Standard Version, Anglicised (NRSVA)
51 Very truly, I tell you, whoever keeps my word will never see death.’ 52 The Jews said to him, ‘Now we know that you have a demon. Abraham died, and so did the prophets; yet you say, “Whoever keeps my word will never taste death.” 53 Are you greater than our father Abraham, who died? The prophets also died. Who do you claim to be?’ 54 Jesus answered, ‘If I glorify myself, my glory is nothing. It is my Father who glorifies me, he of whom you say, “He is our God”, 55 though you do not know him. But I know him; if I were to say that I do not know him, I would be a liar like you. But I do know him and I keep his word. 56 Your ancestor Abraham rejoiced that he would see my day; he saw it and was glad.’ 57 Then the Jews said to him, ‘You are not yet fifty years old, and have you seen Abraham?’[a] 58 Jesus said to them, ‘Very truly, I tell you, before Abraham was, I am.’ 59 So they picked up stones to throw at him, but Jesus hid himself and went out of the temple.
