The number seven in Judaism is a symbol of many issues: seven days in a week, the seventh years that the Hebrew servant can be free and more. Also for the festival of Purim this number is found when we count the number of customs that we have in Month Adar.
Let’s see what the customs are:
The first thing is reading the scroll of Esther- מְגִלַּת אֶסְתֵּר -from the beginning to its end. Mostly this scroll is read in the synagogue in the night of Purim and on the day itself.
The second is to send מִשְׁלוֹחַ מָנוֹת- a fancy food that you give to your friends or your family.
The third is to bring presents for the poor people- מתנות לאביונים. There is a commandment to bring two presents for two people, because this commandment is written in plural form.
The forth and the fifth are to read in the Torah and blessing the prayer “‘al ha-nissim“- על הנסים.
The sixth is to have meal that is called “se’udah“- סעודה- in this meal you should drink more than usual.
The seventh and the last is something that you must not do- you are not allowed to say fast and eulogize in the fourteenth and the fifteenth of Adar.
Happy Purim- חג פורים שמח!
