History of Shavuot: The Feast of Weeks

Reading Time: 2 minutes

Tonight at sundown begins the Jewish holiday Shavuot, also known as the Feast of Weeks, and continues until sundown on May 23

The holiday, also known in Greek as Pentecost, is on the sixth day of the Hebrew lunarsolar calendar month of Sivan, which means that in the Gregorian solar calendar, it may occur between May 15 and June 14. However, the holiday of Pentecost, in the Christian calendar at least, while it also counts from the date of Passover, is always on a Sunday, the seventh Sunday after Easter. In contrast, the Jewish holiday is fixed on the Hebrew date of 6 Sivan.

Shavuot, or Shavuos, is called the “Feast of Weeks” because it occurs seven weeks (7 × 7 days) or 50 days (inclusive) after the first day of the Jewish Passover. It is distinguished from the Christian Passover in that its date is tied to Easter, as determined at the Christian ecumenical Council of Nicaea in A.D. 325.

Shavuot is one of the three “Pilgrimage festivals,” holidays when work was forbidden, and Jews were to bring their sacrifices to the Temple in Jerusalem.

 

Historical Context of Shavuot

According to Exodus 34:22, Shavuot marked the grain harvest in the ancient land of Israel. The harvest lasted seven weeks. Similarly, the eighth day of Sukkot was the festival of the fruit harvest.

According to Leviticus 23:15, the “Counting of Omar” between Pentecost and Shavuot refers to the measure (omer) of barley that was offered at the Temple of Jerusalem. The traditional offering was two loaves of bread from the grain harvest.

It is also commonly believed that 49 days (seven weeks) passed between the Exodus of the Children of Israel from Egypt and the giving of the Ten Commandments to Moses at Mount Sinai, traditionally set in 1312 B.C.

It is celebrated worldwide for two days, but in modern Israel, it is a holiday for only one day.

After the destruction of the Jerusalem Temple in 70 A.D., rabbinic observances governed the customs of Shavuot. These include prayers, reading liturgical poems, and the Hebrew Bible—especially the Torah and Ruth (the events of Ruth are during harvest time)—a blessing said over wine, sharing meals, and decorating homes and synagogues with greenery.

Shavuot foods include various dairy foods; according to rabbinic tradition, King Solomon compared the Torah to milk.

These dishes include cheesecake, blintzes, cheese ravioli, and small dumplings. Meat is usually served as the evening meal.

In a modern Jewish kibbutz, the Bikkurim ceremony occurs, the festival of bringing in the first fruits.

 

Christian Connection to Shavuot

Pentecost

In the New Testament book of Acts, Jesus ordered his Disciples to wait in Jerusalem for the gift of the Holy Spirit. This outpouring of the Holy Spirit occurs on Shavuot or Pentecost. In the 1st century, Jewish and Christian Pentecosts occurred simultaneously.

 

Conclusion

While Shavuot, or Pentecost, is one of the least familiar Jewish holidays, even among modern Jews, and lacks the pageantry of some other Jewish feast days, it is a reminder of harvest and joy, and a look back to Passover for Jews and to Easter for Christians.

      LATHIN 77,

      Thanks for the question.

      There are two parts to the answer:

      1) Some holidays are fixed to a date that is the same every year. Others are fixed to a day of the week, that may change every year.

      2) I suspect, however, you’re wondering about the difference between the Jewish Pentecost and the Christian Pentecost. Initially, they were the same.

      Short answer: The first Christian Pentecost, as recorded in Acts 2, occurred on the Jewish festival of Shavuot, which falls fifty days after Passover. The Christian holiday inherited both the name and the date directly from the Jewish calendar.

      Longer answer: In 325 AD, at the Council of Nicaea, the Emperor Constantine wanted to separate Christian Easter from Jewish Passover. Different bishops in different parts of the Roman Empire celebrated Easter on different dates. Constantine standardized the date of Easter across the Empire. See my link in the article to the Council of Nicaea for more details. https://billpetro.com/history-of-easter/#:~:text=Date%20of%20Easter,that%20may%20differ%20from%20year%20to%20year.
