Esther 9:23–28

The edict carried out

So the Jews agreed to continue the celebration they had begun, doing what Mordecai had written to them. 24 For Haman son of Hammedatha, the Agagite, the enemy of all the Jews, had plotted against the Jews to destroy them and had cast the pur (that is, the lot) for their ruin and destruction. 25 But when the plot came to the king’s attention, he issued written orders that the evil scheme Haman had devised against the Jews should come back onto his own head, and that he and his sons should be hanged on the gallows. 26 (Therefore these days were called Purim, from the word pur.) Because of everything written in this letter and because of what they had seen and what had happened to them, 27 the Jews took it upon themselves to establish the custom that they and their descendants and all who join them should without fail observe these two days every year, in the way prescribed and at the time appointed. 28 These days should be remembered and observed in every generation by every family, and in every province and in every city. And these days of Purim should never cease to be celebrated by the Jews, nor should the memory of them die out among their descendants.

We do not know how readily religious Jews accepted a holiday ordered by secular leaders who were not priests or prophets of God. But Purim became established as a Jewish holiday and is still celebrated. It is not mentioned in the New Testament but is mentioned in the Apocrypha and by Josephus. Shortly after the time of Christ, a whole section of the worship regulations recorded in the Jewish traditions, the Mishnah, was devoted to this holiday.
