Esther 9:25-27

New Catholic Bible

²⁵ But when Esther entered the royal presence, the king gave written orders that the wicked scheme Haman had devised against the Jews should be turned against him instead and that he and his sons should be hanged on gibbets. ²⁶ (Therefore, these days were called Purim,^[a] from the word pur.)

Because of everything mentioned in this letter and because of what they had seen and what they had experienced, ²⁷ the Jews took upon themselves, their descendants, and any who should join them,^[b] the inviolable obligation to celebrate these two days every year in the way prescribed and at the time appointed.
