Esther 9:24–28

²⁴For Haman son of Hammedatha the Agagite, the enemy of all the Jews, ^jhad plotted against the Jews to destroy them. He cast the Pur (that is, the lot) to crush and destroy them. ^k25But when the matter was brought before the king, ^lhe commanded by letter that the evil plan Haman had devised against the Jews return on his own head ^mand that he should be hanged with his sons on the gallows. ⁿ²⁶For this reason these days are called Purim, from the word Pur. ^o

Because of all the instructions in this letter as well as what they had witnessed and what had happened to them, ²⁷the Jews bound themselves, their descendants, and all who joined ^pwith them to a commitment that they would not fail to celebrate these two days each and every year according to the written instructions and according to the time appointed. ²⁸These days are remembered and celebrated by every generation, family, province, and city, so that these days of Purim will not lose their significance in Jewish life ^qand their memory will not fade from their descendants. ^r
