John 13:35-38
English Standard Version
Chapter 13
35By this all people will know that you are my disciples, if you have love for one another."
36Simon 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."
37Peter said to him, "Lord, why can I not follow you now? I will lay down my life for you."
38Jesus 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.
