1. The Gemara explains that the cities of Lod and Ono were walled from the times of Yehoshua bin Nun.
2. Women are obligated to hear the reading of the Megilah.
3. Moshe Rabeinu instituted that one must learn the laws of each holiday on that holiday.

A BIT MORE
1. Even though there are verses that state that others built these cities, they actually were destroyed (during the war of Pilegesh b'Giv'ah) and were immediately rebuilt by Afla'el, and then restored later by Asa.
2. Women were also involved in the miracle of Purim. (See Rashi and Tosfos for two different explanations of this statement.)
3. Even though we do not read the Megilah on Purim when it falls on Shabbos (and instead read it on Sunday), we do have to learn the laws of Purim on that Shabbos.
4. This is in order to prevent someone from accidentally carrying a Megilah four Amos in Reshus ha'Rabim.
5. Since the poor people look forward to the day the Megilah is read since they expect to receive Matanos l'Evyonim, the money is always given on the day the Megilah is read. However, the people in the villages held their Purim meal on the same day as everyone else.
