3 When Judas, his betrayer, saw that he was condemned, he repented and brought back the thirty pieces of silver to the chief priests and the elders, 4 saying, “I have sinned in betraying innocent blood.” They said, “What is that to us? See to it yourself.” 5 And throwing down the pieces of silver in the temple, he departed; and he went and hanged himself.

20 When it was evening, he sat at table with the twelve disciples;[a] 21 and as they were eating, he said, “Truly, I say to you, one of you will betray me.” 22 And they were very sorrowful, and began to say to him one after another, “Is it I, Lord?” 23 He answered, “He who has dipped his hand in the dish with me, will betray me. 24 The Son of man goes as it is written of him, but woe to that man by whom the Son of man is betrayed! It would have been better for that man if he had not been born.” 25 Judas, who betrayed him, said, “Is it I, Master?”[b] He said to him, “You have said so.”
