Esther 9:27-29

Complete Jewish Bible

²⁷ the Jews resolved and took upon themselves, their descendants and all who might join them that without fail they would observe these two days in accordance with what was written in [this letter] and at the appointed time, every year; ²⁸ and that these days would be remembered and observed throughout every generation, every family, every province and every city; and that these days of Purim would never cease among the Jews or their memory be lost by their descendants.

²⁹ Then Ester the queen, the daughter of Avichayil, and Mordekhai the Jew, gave full written authority to confirm a second letter about Purim.
