The Omer Period
What is the Omer Period and why do we observe it?
In Temple times, a sheaf of barley was brought to the Temple in Jerusalem each day starting on 2nd Day Pesach and continuing for 49 days until Shavuot.
An omer was a sheaf of barley which was brought to the Temple as an offering on the second day of Pesach (Passover). This marked the beginning of the harvest season. It is written in the Bible:
"When you enter the land which I am giving to you and reap its harvest, you shall bring the first sheaf of your harvest to the priest the priest shall wave it on the day after the Sabbath."
'The Sabbath' here actually means ‘holy day’, and refers to Passover.
God told the Jews to bring an offering of their first harvest to the Temple, and He would then show concern for the rest of their grains.
Vayikra (Leviticus) 23: 15-16 commands:
"From the day that you bring the sheaf offering, you shall keep count until seven full weeks have elapsed; you shall count 50 days until the day after the seventh week (Shavuot); then you shall bring an offering of new grain to Adonai."
So, from the day of the offering, we are instructed to count 49 days until the festival of Shavuot (Feast of Weeks). This seven-week interval is called the Omer (more formally it is called Sefirat haOmer or 'the Counting of the Omer'). The practice of bringing a sheaf of barley to the Temple was discontinued following the destruction of the Second Temple; howeve,r the counting of the Omer (Sefirat Ha’Omer) and the celebration of Shavuot continue to this day.
The 33rd day of the Omer is called Lag B’Omer and it is a day of exemption from mourning. Two events are thought to have occurred on Lag B’Omer; the first a cessation of the plague affecting Rabbi Akiva’s students and second, it is the day that the revolutionary Bar Kochba succeeded in driving the Romans out of Palestine in 132 C.E.
How do we observe the Omer Period?
The period of the Omer is one of semi-mourning. One of the interpretations given for this is that in Second Temple times many of Rabbi Akiva’s students died during this season either from a plague or because they were killed by the Romans. This period also reminds us that we should try improve our behaviour so that when we receive the Torah (on Shavuot), we will be ready. Hence, we are prohibited from doing certain things, such as:
- Cutting our hair (or shaving)
- Having weddings or parties
- Listening to music
Synagogue Services for Sefirat haOmer
The counting of the Omer begins on Second Day Pesach during the Ma’ariv (evening) service. The passage from Vayikra (above) is read, followed by the benediction:
"Blessed are You, Adonai our God, Ruler of the Universe, who has hallowed us with your commandments, and commanded us concerning the Counting of the Omer."
Thirdly, we announce the number of weeks that have passed since the start of the count. For example, "Today is the twelfth day making one week and 5 days of the Omer."
