Matthew 26:75
Douay-Rheims
And 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.
Rabanus Maurus
After the third denial comes the cock-crow; by which we may understand a Doctor of the Church who with chiding rouses the slumbering, saying, Awake, ye righteous, and sin not. (1 Cor. 15:14.) Thus Holy Scripture uses to denote the merit of divers cases1 by fixed periods, as Peter sinned at midnight and repented at cock-crow.
