Mark 14:70-72

Young's Literal Translation

⁷⁰ and he was again denying. And after a little again, those standing near said to Peter, `Truly thou art of them, for thou also art a Galilean, and thy speech is alike;'

⁷¹ and he began to anathematize, and to swear -- `I have not known this man of whom ye speak;'

⁷² and a second time a cock crew, and Peter remembered the saying that Jesus said to him -- `Before a cock crow twice, thou mayest deny me thrice;' and having thought thereon -- he was weeping.
