It was to celebrate a time when the Jews got rid of their enemies. They were also to celebrate it as the month their sadness was turned to joy. It was the month when their crying for the dead was turned into celebration. Mordecai wrote letters to all the Jews. He wrote to tell them to celebrate those days as days of joyful feasting. It was to be a time of giving food to each other. And it was a time of giving presents to the poor.
