Esther 9:30-32

Young's Literal Translation

³⁰ and he sendeth letters unto all the Jews, unto the seven and twenty and a hundred provinces of the kingdom of Ahasuerus -- words of peace and truth --

³¹ to establish these days of Purim, in their seasons, as Mordecai the Jew hath established on them, and Esther the queen, and as they had established on themselves, and on their seed -- matters of the fastings, and of their cry.

³² And a saying of Esther hath established these matters of Purim, and it is written in the Book.
