Now it came to pass in the days of (a) Ahasuerus, (this [is] Ahasuerus which reigned, from India even unto Ethiopia, [over] an (b) hundred and seven and twenty provinces:)
The Argument - Because of the variety of names, by which they used to call their kings, and the number of years in which the Hebrews and the Greeks vary, various authors write concerning that Ahasuerus but is seems in (Daniel 6:1; Daniel 9:1) that he was Darius king of the Medes and son of Astyages also called Ahasuerus which was a name of honour and signified great and chief as chief head. In this is declared the great mercies of God toward his church: who never fails them in their greatest dangers, but when all hope of worldly help fades, he stirs up some, by whom he sends comfort and deliverance. In this also is described the ambition, pride and cruelty of the wicked when they come to honour and their sudden fall when they are at their highest and how God preserves and prefers them who are zealous of his glory and have a care and love for their brethren.
(a) Also called Darius, who was now the favourite monarch and had the government of the Medes, Persians and Chaldeans. Some think he was Darius Hystaspis also called Artaxerxes.
(b) (Daniel 6:1) makes mention of only 120 leaving out the number that are imperfect as the scripture uses in various places.
