Matthew 26:69-75 (Douay-Rheims 1899 American Edition.)
69But Peter sat without in the court: and there came to him a servant maid, saying: Thou also wast with Jesus the Galilean.
70But he denied before them all, saying: I know not what thou sayest.
71And as he went out of the gate, another maid saw him, and she saith to them that were there: This man also was with Jesus of Nazareth.
72And again he denied with an oath, I know not the man.
73And after a little while they came that stood by, and said to Peter: Surely thou also art one of them; for even thy speech doth discover thee.
74Then he began to curse and to swear that he knew not the man. And immediately the cock crew.
75And Peter remembered the word of Jesus which he had said: Before the cock crow, thou wilt deny me thrice. And going forth, he wept bitterly.
