Esther 9:26-32

26 Wherefore they called these yamim Purim after the shem of the Pur. Therefore for all the words of this iggeret (letter), and of that which they had seen concerning this matter, and which had happened unto them,
27 The Yehudim established, and took upon them, and upon their zera, and upon all such as joined themselves unto them, so as it should not fail, that they would keep these two days according to their writing, and according to their appointed time shanah v’shanah;
28 And that these yamim should be remembered and kept dor v’dor (throughout every generation), in every mishpachah, every province, and every city; and that these yemei HaPurim should never cease from among the Yehudim, nor the memorial of them perish from their zera.
29 Then Ester HaMalkah, the bat Avichayil, and Mordechai HaYehudi, wrote with kol tokef (all authority, see Yn 1:12-13), to confirm this second iggeret (letter of) Purim.
30 And he sent seferim unto all the Yehudim, to the hundred twenty and seven provinces of the malchut of Achashverosh, with words of shalom and emes,
31 To confirm these yemei HaPurim in their times appointed, according as Mordechai HaYehudi and Ester HaMalkah had enjoined them, and as they had decreed for themselves and for their zera, the matters of the tzomot (fasts) and their ze’akah (lamentation).
32 And the decree of Ester confirmed these matters of Purim; and it was written in the sefer.
