John 13:36-38

36 Simon Peter said to him, "Lord, where are you going?" Jesus answered, "Where I am going, you cannot follow me now; but you will follow afterward."
37 Peter said to him, "Lord, why can I not follow you now? I will lay down my life for you."
38 Jesus answered, "Will you lay down your life for me? Very truly, I tell you, before the cock crows, you will have denied me three times.
