the Jews agreed to continue. It became a tradition for them, their children, and all future converts to remember these two days every year on the specified dates set down in the letter.
These days are to be remembered and kept by every single generation, every last family, every province and city. These days of Purim must never be neglected among the Jews; the memory of them must never die out among their descendants.
Queen Esther, the daughter of Abihail, backed Mordecai the Jew, using her full queenly authority in this second Purim letter
to endorse and ratify what he wrote. Calming and reassuring letters went out to all the Jews throughout the 127 provinces of Xerxes' kingdom

Esther's word confirmed the tradition of Purim and was written in the book.
