John 13:33-38

Little children, yet a little while I am with you. You will seek me, and just as I said to the Jews, so now I also say to you, ‘Where I am going you cannot come.’ A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.” 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.” Peter said to him, “Lord, why can I not follow you now? I will lay down my life for you.” 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.
