Luke 22:60-62King James Version (KJV)
60 And Peter said, Man, I know not what thou sayest. And immediately, while he yet spake, the cock crew.
61 And the Lord turned, and looked upon Peter. And Peter remembered the word of the Lord, how he had said unto him, Before the cock crow, thou shalt deny me thrice.
62 And Peter went out, and wept bitterly.
