'Cock' in the Bible

And Jesus said to him, 'Verily I say to thee, that to-day, this night, before a cock shall crow twice, thrice thou shalt deny me.'

and he denied, saying, 'I have not known him, neither do I understand what thou sayest;' and he went forth without to the porch, and a cock crew.

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.
