Festivals in Ancient Israel

Three agriculture-related pilgrimage festivals are mandated in Exodus 23:14-17, a seven-day springtime festival of Unleavened Bread, around the barley harvest; an early summer festival of Harvest, when the wheat ripens; and an autumn festival of Ingathering, when olives, grapes, and other fruits are harvested (Exod 34:18-23).

The book of Leviticus gives regulations for feast days that are to be celebrated "with a sacred assembly," including the weekly sabbath (Lev 23:1-4) and seven annual feast days: Passover (7 days, incl. unleavened bread), First fruits, Pentecost or Weeks, the New Year, the Day of Atonement, the first day of Booths, and the eighth day of Booths (Lev 23:5-44)

These festivals were later combined with commemorations of historical/religious events, and while the people were originally allowed to bring their offerings to any major sanctuary, they were later required to go to the Jerusalem temple, most importantly for the three main pilgrimage festivals listed next, (Deut 16:1-17).

Feast of Passover (Pesach) and Unleavened Bread (Mazzot)

Feast of Weeks (Pentecost or Shavuot)

Feast of Booths (Tabernacles or Sukkoth)

Other Feasts and Special Days

New Testament

The Synoptic Gospels have only one Passover meal that Jesus celebrates just before his death (Mark 14:12-26, Matt 26:17-29, Luke 22:15-20)

The Fourth Gospel reports three different Passovers during Jesus' public ministry (John 2:13-23, John 6:4, John 11:55) but never mentions "Unleavened Bread"), as well as the festival of Booths.

In the Book of Acts it is said that after the resurrection of Jesus his disciples remained in Jerusalem until Pentecost (Acts 2:1), when they received the outpouring of the Holy Spirit. Acts also records how, several years later, James was killed and Peter arrested during the feast of Unleavened Bread, although Peter is miraculously delivered from the prison just after the Passover feast had concluded (Acts 12:1-4).

Finally, Acts also reports that a few decades later, Paul and his companions leave Philippi just after the feast of Unleavened Bread (Acts 20:6), and that Paul wishes to reach Jerusalem in time for the next pilgrimage festival, the day of Pentecost (Acts 20:16).

In Paul's letters, he once refers to Christ as "our Passover" or "paschal lamb" (1 Cor 5:7). Later in the same letter he also tells the Corinthians, "I shall stay in Ephesus until Pentecost" (1 Cor 16:8).

Finally, the Letter to the Hebrews once mentions the original Passover at the time of Moses (Heb 11:28).
