Matthew 26:71KJV

69But he denied before all, saying, I know not what thou sayest.

70And when he was gone out into the porch, another saw him, and said unto them that were there, This was also with Jesus of Nazareth.

71And again he denied with an oath, I do not know the man.

72And after a while came unto they that stood by, and said to Peter, Surely thou also art of them; for thy speech bewrayeth thee.

73Then began he to curse and to swear, , I know not the man. And immediately the cock crew.
