Esther 9:31-32

American Standard Version

³¹ to confirm these days of Purim in their appointed times, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had ordained for themselves and for their seed, in the matter of the fastings and their cry. ³² And the commandment of Esther confirmed these matters of Purim; and it was written in the book.
