Shavuot, the Feast of Weeks or Pentecost as it is called in the New Covenant, is a late spring holiday that is observed on the Hebrew calendar date Sivan 6. While most Christians know of the powerful events of Pentecost as recorded in Acts, chapter 2, very few are aware of the historical yearly observance that pointed toward it. It is important to understand the Old Covenant observance of Shavuot and its historical meaning to fully appreciate its New Covenant fulfillment. This feast, once thought of as only a Church holiday, is actually one of the biblical mo’adim—appointments with God—and is rich with meaning and significance.
