Purim is a Jewish holiday which commemorates the saving of the Jewish people from Haman, a Persian Empire official who was planning to kill all the Jews, as recounted in the Book of Esther. The book shares with The Song of Songs the curious distinction of never once mentioning God.
The wholesale destruction of the enemies of the Jews is narrated in chapter 9:6
‘Meanwhile, the remainder of the Jews who were in the king’s provinces also assembled to protect themselves and get relief from their enemies. They killed seventy-five thousand of them.’
This genocide of 75,000 people is never mentioned during the Purim celebrations (also called the Jewish Mardi Gras). Only the joy of the Jews at their deliverance matters.
The Bible’s violent verses tend to get ignored.
