John 13:36-38 (ESV)
Jesus Foretells Peter’s Denial
36 Simon Peter said to him, “Lord, where are you going?” Jesus answered him, “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? Truly, truly, I say to you, the rooster will not crow till you have denied me three times.
