Jamieson, Fausset and Brown on Esther 3:12-15

12-15. Then were the king's scribes called ... and there was written--The government secretaries were employed in making out the proclamation authorizing a universal massacre of the Jews on one day. It was translated into the dialects of all the people throughout the vast empire, and swift messengers were sent to carry it into all the provinces. On the day appointed, all Jews were to be put to death and their property confiscated; doubtless, the means by which Haman hoped to pay his stipulated tribute into the royal treasury. To us it appears unaccountable how any sane monarch could have given his consent to the extirpation of a numerous class of his subjects. But such acts of frenzied barbarity have, alas! been not rarely authorized by careless and voluptuous despots, who have allowed their ears to be engrossed and their policy directed by haughty and selfish minions, who had their own passions to gratify, their own ends to serve.
