John 13:36-38 - Peter's Denials Predicted
36 Simon Peter said unto him, "Lord whither goest thou?" Jesus answered him, "Whither I go thou canst not follow me now, but thou shalt follow me afterwards."
37 Peter said unto him, "Lord why cannot I follow thee now? I will give my life for thy sake."
38 Jesus answered him, "Wilt thou give thy life for my sake? Verily, verily I say unto thee, the cock shall not crow, till thou have denied me thrice."
