Esther 3:7

7 In the twelfth year of King Xerxes' rule, in the first month, the month of Nisan, Haman ordered the lots to be cast ("purim," they were called) to find out the right day and month to carry out his plot. The thirteenth day of the twelfth month, the month of Adar, was decided on.

Esther 3:7 In-Context

5 Haman was furious when he realized that Mordecai was not going to kneel and bow to him,
6 and when he learned that Mordecai was a Jew, he decided to do more than punish Mordecai alone. He made plans to kill every Jew in the whole Persian Empire.
7 In the twelfth year of King Xerxes' rule, in the first month, the month of Nisan, Haman ordered the lots to be cast ("purim," they were called) to find out the right day and month to carry out his plot. The thirteenth day of the twelfth month, the month of Adar, was decided on.
8 So Haman told the king, "There is a certain race of people scattered all over your empire and found in every province. They observe customs that are not like those of any other people. Moreover, they do not obey the laws of the empire, so it is not in your best interests to tolerate them.
9 If it please Your Majesty, issue a decree that they are to be put to death. If you do, I guarantee that I will be able to put 375 tons of silver into the royal treasury for the administration of the empire."
