John 13:38 ASV

³⁶  Simon Peter saith unto him, Lord, whither goest thou? Jesus answered, Whither I go, thou canst not follow now; but thou shalt follow afterwards.

³⁷  Peter saith unto him, Lord, why cannot I follow thee even now? I will lay down my life for thee.

³⁸  Jesus answereth, Wilt thou lay down thy life for me? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.
