Esther 9:21-23

Revised Standard Version

²¹ enjoining them that they should keep the fourteenth day of the month Adar and also the fifteenth day of the same, year by year, ²² as the days on which the Jews got relief from their enemies, and as the month that had been turned for them from sorrow into gladness and from mourning into a holiday; that they should make them days of feasting and gladness, days for sending choice portions to one another and gifts to the poor.

²³ So the Jews undertook to do as they had begun, and as Mor′decai had written to them.
