Esther 3:7

In the first month, that is, the month Nisan, in the twelfth year of King Ahasuerus, they cast Pur, that is, the lot, before Haman from day to day and from month to month, the court astrologers and magicians being entrusted with this work of determining which day and month would be the most auspicious for carrying out Haman's murderous design, to the twelfth month, that is, the month Adar, for Haman, with a zeal and persistence worthy of a better cause, determined that all signs must be favorable for the execution of his plan. The text is evidently to be understood in such a way that Haman, in the first month of the Jewish year, caused the lot to be cast, first for the month of the coming year in which he intended to have his revenge, and then for the day of the month which would be auspicious for his scheme. The fact that the last month of the Jewish year was chosen by lot gave him ample time to prepare his plans. Thus the enemies of the Church, Satan and the world, are always busy with schemes of destruction, which God, however, can easily frustrate at His own time.
