Esther 9:31-32
Wycliffe Bible
31 and that they should keep the days of lots, and hallow them with joy in their time, as Mordecai and Esther had ordained; and they received the (rules for the) fastings, and the cries, and the days of lots, to be kept of themselves and of their seed, (and so that they would keep the Days of Purim, that is, the Days of Lots, and celebrate them with joy at their proper time, as Mordecai and Esther had ordained; just as they had received the rules for fasting, and mourning, or lamenting, to be kept by themselves, and by their descendants.)
32 and they received all things that be contained in the story of this book, that is called Esther. (And so Esther’s command confirmed these rules for Purim, or Lots, that be contained in this book.)
