“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:) / That in those days, when the king Ahasuerus sat on the throne of his kingdom, which was in Shushan the palace, / In the third year of his reign, he made a feast unto all his princes and his servants; the power of Persia and Media, the nobles and princes of the provinces, being before him: / When he shewed the riches of his glorious kingdom and the honour of his excellent majesty many days, even an hundred and fourscore days.”
