Gospel: John 13:21-33, 36-38

²¹ When Jesus had thus spoken, he was troubled in spirit, and testified, “Truly, truly, I say to you, one of you will betray me.”
²² The disciples looked at one another, uncertain of whom he spoke.
²³ One of his disciples, whom Jesus loved, was lying close to the breast of Jesus;
²⁴ so Simon Peter beckoned to him and said, “Tell us who it is of whom he speaks.”
²⁵ So lying thus, close to the breast of Jesus, he said to him, “Lord, who is it?”
²⁶ 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.
²⁷ Then after the morsel, Satan entered into him. Jesus said to him, “What you are going to do, do quickly.”
²⁸ Now no one at the table knew why he said this to him.
²⁹ 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.
³⁰ So, after receiving the morsel, he immediately went out; and it was night.
³¹ When he had gone out, Jesus said, “Now is the Son of man glorified, and in him God is glorified;
³² if God is glorified in him, God will also glorify him in himself, and glorify him at once.
³³ 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.’
³⁶ 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.”
³⁷ Peter said to him, “Lord, why cannot I 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 cock will not crow, till you have denied me three times.
