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, to the twelfth month, that is, the month Adar.”
KJV
Read in Esther 3Meaning
The casting of lots gives the planned attack a scheduled date but does not make Haman's violence legitimate or divinely approved. The date later becomes central to the reversal celebrated in Purim.
