John 13:36-38

36 Simon Peter said to him, "Lord, where are you going?" Jesus answered, "Where I am going, you can't follow now, but you will follow afterwards."

37 Peter said to him, "Lord, why can't I follow you even now? I will lay down my life for you."

38 Jesus answered him, "Will you lay down your life for me? Most assuredly I tell you, the rooster won't crow until you have denied me three times.
