Esther 1:1, 22

Now it came to pass in the days of Ahasuerus (this was the Ahasuerus who reigned over one hundred and twenty-seven provinces, from India to Ethiopia)

Then he sent letters to all the king’s provinces, to each province in its own script, and to every people in their own language, that each man should be master in his own house, and speak in the language of his own people.
