Esther (Greek) 9:29

²⁷And Mordecai established it, and the Jews took upon themselves, and upon their seed, and upon those that were joined to them to observe it, neither would they on any account behave differently: but these days were to be a memorial kept in every generation, and city, and family, and province.

²⁸And these days of the Purim, said they, shall be kept forever, and their memorial shall not fail in any generation.

— Esther (Greek) 9:29 —

³¹And Mordecai and Esther the queen appointed a fast for themselves privately, even at that time also having formed their plan against their own health.
