Matthew 26:24-25, 34

The Son of man goeth, even as it is written of him: but woe unto that man through whom the Son of man is betrayed! good were it for that man if he had not been born. And Judas, who betrayed him, answered and said, Is it I, Rabbi? He saith unto him, Thou hast said.

Jesus said unto him, Verily I say unto thee, that this night, before the cock crow, thou shalt deny me thrice.
