Esther 9:27-29

Revised Standard Version Catholic Edition

²⁷ the Jews ordained and took it upon themselves and their descendants and all who joined them, that without fail they would keep these two days according to what was written and at the time appointed every year, ²⁸ that these days should be remembered and kept throughout every generation, in every family, province, and city, and that these days of Purim should never fall into disuse among the Jews, nor should the commemoration of these days cease among their descendants.

²⁹ Then Queen Esther, the daughter of Ab′ihail, and Mor′decai the Jew gave full written authority, confirming this second letter about Purim.
