Question
What are the biblical feasts and festivals? (the appointed times of Leviticus 23, Passover, Pentecost, the Day of Atonement, Tabernacles, and more)
Analysis
The spring feasts
Passover, Unleavened Bread, and Firstfruits fall together in the first month and center on the exodus and the early harvest. Passover looks back to the night the LORD "passed over" Israel's blood-marked homes in Egypt (Exodus 12:13); Unleavened Bread recalls the haste of leaving, with no time for bread to rise (Exodus 12:39); Firstfruits gives God the first of the barley harvest, a pledge that the rest belongs to Him (Leviticus 23:10). Weeks/Pentecost closes the spring cycle fifty days later with the wheat harvest (Leviticus 23:16; Exodus 34:22).
The fall feasts
The seventh month holds three holy days in quick succession: Trumpets opens it with a day of blasts (Leviticus 23:24); ten days later comes the Day of Atonement, the one day the high priest entered the Most Holy Place to cleanse the sanctuary and the people, with two goats, one sacrificed, one sent into the wilderness bearing the nation's guilt (Leviticus 16:7; Leviticus 16:10; Leviticus 16:34); and five days after that, Tabernacles, a joyful week in booths that both remembers the wilderness and celebrates the final harvest (Leviticus 23:39; Leviticus 23:43).
A Christian reading (one lens, attributed)
Many Christians have read the feasts as pointing forward to Christ, Paul calls Christ "our Passover lamb" (1 Corinthians 5:7); the Spirit was poured out on the day of Pentecost (Acts 2:1); and Hebrews reads the Day of Atonement as fulfilled in Christ's once-for-all offering (Hebrews 9:11; Hebrews 9:12). This typological reading is a widely held interpretation, not a claim Leviticus 23 makes of itself, the chapter describes what Israel was to keep and why. Jewish tradition keeps these same appointed times as the enduring festival calendar.
