John 13:31-38 New English Translation (NET Bible)
The Prediction of Peter’s Denial
31 When Judas had gone out, Jesus said, “Now the Son of Man is glorified, and God is glorified in him. 32 If God is glorified in him, God will also glorify him in himself, and he will glorify him right away. 33 Children, I am still with you for a little while. You will look for me, and just as I said to the Jewish religious leaders, ‘Where I am going you cannot come,’ now I tell you the same.
34 “I give you a new commandment—to love one another. Just as I have loved you, you also are to love one another. 35 Everyone will know by this that you are my disciples—if you have love for one another.”
36 Simon Peter said to him, “Lord, where are you going?” Jesus replied, “Where I am going, you cannot follow me now, but you will follow later.” 37 Peter said to him, “Lord, why can’t I follow you now? I will lay down my life for you!” 38 Jesus answered, “Will you lay down your life for me? I tell you the solemn truth, the rooster will not crow until you have denied me three times!
