Mark 14:29

Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended. Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice. Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.

And he said unto him, Lord, I am ready to go with thee, both into prison, and to death.

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. Peter said unto him, Lord, why cannot I follow thee now? I will lay down my life for thy sake. Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.

So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
