Esther 9:25-27

Names of God Bible

²⁵ But when this came to the king’s attention, he ordered, in the well-known letter, that the evil plan Haman had plotted against the Jews should turn back on his own head. As a result, they hung Haman and his sons on poles.

²⁶ So the Jews called these days Purim, based on the word Pur. Therefore, because of everything that was said in this letter—both what they had seen and what had happened to them— ²⁷ the Jews established a tradition for themselves and their descendants and for anyone who would join them. The tradition was that a person should never fail to observe these two days every year, as they were described and at their appointed time.
