Omer

Both Shavuot and Pentecost celebrate the culmination of a fifty-day season in the spring, after Passover and Easter respectively.

Throughout the Bible, we find that the land of Israel is blessed with grain, wine, and oil (דגן, תירוש, ויצהר). In the Torah, however, the festival of Bikkurim, “First Produce,” only celebrates the wheat harvest. In the Temple Scroll, the Essenes rewrote the biblical festival calendar to include two further bikkurim festivals to celebrate wine and oil.

The omer or “sheaf” offering takes place ממחרת השבת, “after the Shabbat” (Leviticus 23:15). Jewish interpreters have debated the exact meaning of this phrase for two millennia, resulting in four different dates being adopted by one Jewish sect or another.
