Matthew 26: 14 - 25
14 Then one of the twelve, who was called Judas Iscariot, went to the chief priests
15 and said, "What will you give me if I deliver him to you?" And they paid him thirty pieces of silver.
16 And from that moment he sought an opportunity to betray him.
17 Now on the first day of Unleavened Bread the disciples came to Jesus, saying, "Where will you have us prepare for you to eat the passover?"
18 He said, "Go into the city to a certain one, and say to him, `The Teacher says, My time is at hand; I will keep the passover at your house with my disciples.'"
19 And the disciples did as Jesus had directed them, and they prepared the passover.
20 When it was evening, he sat at table with the twelve disciples;
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?" He said to him, "You have said so."
