Perintah Ester meneguhkan hal-hal mengenai Purim itu, lalu hal itu dituliskan dalam kitab.
Rashi
On the basis of Esther’s request [these Purim matters] were perpetuated, etc. Esther requested of the Sages of the generation to commemorate her and to write this book with the rest of the Scriptures, and that is the meaning of “and inscribed in the book.”20Maseches Megillah 7a.
