The Feast of Purim, found in the book of Esther, is a celebration of the overturning of a decree of death to the Jews in the ancient Persian Empire. It's amazing to see the correlation between the plot by Hamen and the current regime in Iran which is intent to annhililate Israel and America. There are not the usual public celebrations of the feast going on in Israel today, due to the current situation with missile attacks coming in from Iran, but there is expectation that God will preserve His people, as He did in the days of Esther, Mordecai, and Hamen.
