Matthew 26:72

69 Now Peter was seated in the open square outside the house: and a servant-girl came to him, saying, You were with Jesus the Galilaean.

70 But he said before them all that it was false, saying, I have no knowledge of what you say.

71 And when he had gone out into the doorway, another saw him and says to those who were there, This man was with Jesus the Nazarene.

72 And again he said with an oath, I have no knowledge of the man.

73 And after a little time those who were near came and said to Peter, Truly you are one of them; because your talk is witness against you.

74 Then with curses and oaths he said, I have no knowledge of the man. And straight away there came the cry of a cock.

75 And the word of Jesus came back to Peter, when he said, Before the hour of the cock's cry, you will say three times that you have no knowledge of me. And he went out, weeping bitterly.
