15 The posts went out, being hastened by the king's commandment, and the decree was given in Shushan the palace. And the king and Haman sat down to drink; but the city Shushan was perplexed.
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.”
“And the decree was immediately issued in Shushan; and the king and Haman were attending the feast while all the Jews in the city were crying.” This is what the Savior preached to his disciples in the Gospel: “Amen, amen I say to you that you will cry and weep, while the world rejoices; and though you will be sad, your sadness will turn to joy” (John 16).
