36 Simon Peter said to him, "Lord, where are you going?" Jesus answered, "Where I am going you cannot follow me now; but you shall 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? Truly, truly, I say to you, the rooster will not crow, till you have denied me three times.
