Mark 14:70

And he denied it again This denial was probably addressed to those round the fire. But escape was hopeless. "Surely," said one, "this fellow is one of them;" "Thou art a Galilæan," said another, "and thy speech agreeth thereto." These last words are omitted by Lachmann, Tischendorf, and Tregelles. "Thy speech bewrayeth thee" are the words used by St Matthew (Matthew 26:73). The Galilean burr was rough and indistinct. Hence the Galileans were not allowed to read aloud in the Jewish synagogues.
