Good Morning, Dan.
On the Eve of Purim the Book of Esther is read out loud in its entirety.
The Hebrew name for this precious Book is “The Megilla” which has been carried into our own English language as an idiom meaning something really BIG that is presented or done all at once.
As in:
“I asked her how she was doing, and she gave me the whole MEGILLA about what a lousy year 2020 was! Oy Vey! As if we haven’t ALL been through the same thing!”
Such a nice Purim custom. Would that they'd add Isaiah 53.
We were graced once in our church by a young woman who recited for us, unaided from memory, the whole book of Esther (shorter Protestant version). I remain mightily impressed to this present moment.
