What does Esther 9:22 mean?

These were the days when the Jews found relief from their enemies, and their sadness turned into joy, their mourning into a holiday. Mordecai told them to celebrate by feasting, rejoicing, and sharing food with each other and with those in need. Esther 9:22 - Modern Text Bible

(The holiday is about remembering how things turned around for the Jews, and it's meant to be a time of generosity and happiness.)
