Mark 14:67 (KJV)

And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.

Then the high priest rent his clothes, and saith, What need we any further witnesses?

Ye have heard the blasphemy: what think ye? And they all condemned him to be guilty of death.

And some began to spit on him, and to cover his face, and to buffet him, and to say unto him, Prophesy: and the servants did strike him with the palms of their hands.

And as Peter was beneath in the palace, there cometh one of the maids of the high priest:

But he denied, saying, I know not, neither understand I what thou sayest. And he went out into the porch; and the cock crew.

And a maid saw him again, and began to say to them that stood by, This is one of them.

And he denied it again. And a little after, they that stood by said again to Peter, Surely thou art one of them: for thou art a Galilaean, and thy speech agreeth thereto.

But he began to curse and to swear, saying, I know not this man of whom ye speak.

And the second time the cock crew. And Peter called to mind the word that Jesus said unto him, Before the cock crow twice, thou shalt deny me thrice. And when he thought thereon, he wept.
