Matthew 26:21 (KJV)

And from that time he sought opportunity to betray him.

Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the passover?

And he said, Go into the city to such a man, and say unto him, The Master saith, My time is at hand; I will keep the passover at thy house with my disciples.

And the disciples did as Jesus had appointed them; and they made ready the passover.

Now when the even was come, he sat down with the twelve.

And they were exceeding sorrowful, and began every one of them to say unto him, Lord, is it I?

And he answered and said, He that dippeth his hand with me in the dish, the same shall betray me.

The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! it had been good for that man if he had not been born.

Then Judas, which betrayed him, answered and said, Master, is it I? He said unto him, Thou hast said.

And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.
