First Reading ISAIAH 49:1-6
1Listen to me, O coastlands, and hearken, you peoples from afar. The LORD called me from the womb, from the body of my mother he named my name. 2He made my mouth like a sharp sword, in the shadow of his hand he hid me; he made me a polished arrow, in his quiver he hid me away. 3And he said to me, “You are my servant, Israel, in whom I will be glorified.” 4But I said, “I have labored in vain, I have spent my strength for nothing and vanity; yet surely my right is with the LORD, and my recompense with my God.” 5And now the LORD says, who formed me from the womb to be his servant, to bring Jacob back to him, and that Israel might be gathered to him, for I am honored in the eyes of the LORD, and my God has become my strength — 6he says: “It is too light a thing that you should be my servant to raise up the tribes of Jacob and to restore the preserved of Israel; I will give you as a light to the nations, that my salvation may reach to the end of the earth.”
Responsorial Psalm PSALMS 71:1-6, 15, 17
1In thee, O LORD, do I take refuge; let me never be put to shame! 2In thy righteousness deliver me and rescue me; incline thy ear to me, and save me! 3Be thou to me a rock of refuge, a strong fortress, to save me, for thou art my rock and my fortress. 4Rescue me, O my God, from the hand of the wicked, from the grasp of the unjust and cruel man. 5For thou, O Lord, art my hope, my trust, O LORD, from my youth. 6Upon thee I have leaned from my birth; thou art he who took me from my mother’s womb. My praise is continually of thee. 15My mouth will tell of thy righteous acts, of thy deeds of salvation all the day, for their number is past my knowledge. 17O God, from my youth thou hast taught me, and I still proclaim thy wondrous deeds.
Gospel JOHN 13:21-33, 36-38
21When Jesus had thus spoken, he was troubled in spirit, and testified, “Truly, truly, I say to you, one of you will betray me.” 22The disciples looked at one another, uncertain of whom he spoke. 23One of his disciples, whom Jesus loved, was lying close to the breast of Jesus; 24so Simon Peter beckoned to him and said, “Tell us who it is of whom he speaks.” 25So lying thus, close to the breast of Jesus, he said to him, “Lord, who is it?” 26Jesus 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. 27Then after the morsel, Satan entered into him. Jesus said to him, “What you are going to do, do quickly.” 28Now no one at the table knew why he said this to him. 29Some 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. 30So, after receiving the morsel, he immediately went out; and it was night. 31When he had gone out, Jesus said, “Now is the Son of man glorified, and in him God is glorified; 32if God is glorified in him, God will also glorify him in himself, and glorify him at once. 33Little 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.’ 36Simon 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.” 37Peter said to him, “Lord, why cannot I 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 cock will not crow, till you have denied me three times.
