John 13:36-38 - Peter's Denials Predicted
36 Simon Peter said to him: Lord, whither goest thou? Jesus answered him: Whither I go, you can not follow me now; but you shall follow me hereafter.
37 Peter said to him: Lord, why can I not follow thee now? I will lay down my life for thee.
38 Jesus answered him: Will you lay down your life for me? Verily, verily I say to you, the cock will not crow till you have denied me three times.
