"When Jesus had thus spoken, he was troubled in spirit, and testified, "Truly, truly, I say to you, one of you will betray me." The disciples looked at one another, uncertain of whom he spoke. One of his disciples, whom Jesus loved, was lying close to the breast of Jesus; so Simon Peter beckoned to him and said, "Tell us who it is of whom he speaks." So lying thus, close to the breast of Jesus, he said to him, "Lord, who is it?" Jesus answered, "It is he to whom I shall give this morsel when I have dipped it." So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot. Then after the morsel, Satan entered into him. Jesus said to him, "What you are going to do, do quickly." Now no one at the table knew why he said this to him. Some thought that, because Judas had the money box, Jesus was telling him, "Buy what we need for the feast"; or, that he should give something to the poor. So, after receiving the morsel, he immediately went out; and it was night. When he had gone out, Jesus said, "Now is the Son of man glorified, and in him God is glorified; if God is glorified in him, God will also glorify him in himself, and glorify him at once. Little children, yet a little while I am with you. You will seek me; and as I said to the Jews so now I say to you, `Where I am going you cannot come.' A new commandment I give to you, that you love one another; even as I have loved you, that you also love one another. By this all men 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, "Where I am going you cannot follow me now; but you shall follow afterward." Peter said to him, "Lord, why cannot I 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 cock will not crow, till you have denied me three times."
