12 Then were the king's scribes called on the thirteenth day of the first month, and there was written according to all that Haman had commanded unto the king's lieutenants, and to the governors that were over every province, and to the rulers of every people of every province according to the writing thereof, and to every people after their language; in the name of king Ahasuerus was it written, and sealed with the king's ring.
[AD 856] Rabanus Maurus on Esther 3:7-15
The fact that the twelfth month, which is called Adar, was chosen for the destruction of Israel after casting lots is not with its own spiritual meaning. It is referring, in fact, to the grace of Christ which has been prepared for the faithful in the fullness of time when the faithful will undergo a fierce persecution in the world in the last days. And writing about this to Timothy, the teacher of the Gentiles says, “You must understand this, that in the last days distressing times will come. For people will be lovers of themselves, lovers of money, boasters, arrogant, abusive, disobedient to their parents, ungrateful, unholy, inhuman, implacable, slanderers, profligates, brutes, haters of good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, holding the outward form of godliness but denying its power.” And the Lord himself says in the Gospel, “And this gospel of the kingdom will be proclaimed throughout the world, as a testimony to all the nations; and then the end will come.” And a bit further: “For at that time there will be great suffering, such as has not been from the beginning of the world until now, and never will be.”
