Ester 1:1

Now it came to pass in the days of Ahasuerus, (this is Ahasuerus which reigned, from India even unto Ethiopia, over an hundred and seven and twenty provinces:)

Ahasuerus — Many suppose this to be Darius Hystapas, for his kingdom was thus vast, and he subdued India, as Herodotus reports: and one of his wives was called Atossa, differing little from Hadassah, which is Esther's other name, Esther 2:7.

Provinces — So seven new provinces were added to those hundred and twenty mentioned, Daniel 6:1.
