India
India appears in scripture as the eastern boundary of the Persian empire under Ahasuerus, paired in two verses with Ethiopia as the western bound. Both occurrences belong to the book of Esther and frame the geographic scale of the events narrated there.
The Eastern Limit of Ahasuerus
The opening verse of Esther sets the scene by naming the reach of the king's authority: "Now it came to pass in the days of Ahasuerus (this is Ahasuerus who reigned from India even to Ethiopia, over a hundred and seven and twenty provinces)" (Esther 1:1). India and Ethiopia mark the outer edges; between them lie one hundred twenty-seven provinces.
The Edict of Mordecai
The same span is named again when Mordecai's counter-edict is dispatched: the king's scribes write "to the satraps, and the governors and princes of the provinces which are from India to Ethiopia, a hundred twenty and seven provinces, to every province according to its writing, and to every people after their language, and to the Jews according to their writing, and according to their language" (Esther 8:9). The repetition fixes the empire's geographic scope at the moment when the Jewish people are granted the right to defend themselves: the decree must travel from one named horizon to the other.
