Esther 9:24–28

²⁴because Haman, the son of Hammedatha the Agagite, the enemy of all the Jews, ^xhad plotted against the Jews to annihilate them, and had cast Pur (that is, the lot), to consume them and destroy them; ²⁵but ^ywhen ²Esther came before the king, he commanded by letter that ³this wicked plot which Haman had devised against the Jews should ^zreturn on his own head, and that he and his sons should be hanged on the gallows.

²⁶So they called these days Purim, after the name ⁴Pur. Therefore, because of all the words of ^athis letter, what they had seen concerning this matter, and what had happened to them, ²⁷the Jews established and imposed it upon themselves and their descendants and all who would ^bjoin them, that without fail they should celebrate these two days every year, according to the written instructions and according to the prescribed time, ²⁸that these days should be remembered and kept throughout every generation, every family, every province, and every city, that these days of Purim should not fail to be observed among the Jews, and that the memory of them should not perish among their descendants.
