The Feasts of Weeks (Leviticus 23:15-22), known as the day of Pentecost in the New Testament (Acts 2:1), is one of the seven feasts or festivals God commanded His people to commemorate (see Leviticus 23). The Feast of Weeks, a spring harvest festival, is also one of the three major feasts where the worshipers were required to come to the temple in Jerusalem to offer their sacrifices (Deuteronomy 16:1-16). In the New Testament, the day of Pentecost was celebrated fifty days after Passover, the day Jesus died (John 18:28). It’s remembered as the birthday of the church, the day God gave the Holy Spirit to indwell believers in Christ and bonded His children into His family (Romans 8:15-16). Imitating the practices of the early church today, God’s people continue to grow as a community, fellowship together, joyfully worship Him, earnestly study the Bible, lovingly care for one another, and boldly proclaim Jesus as Savior to the unbelieving world (Acts 2:42-48).
