📖 Biblical Definition
The Feast of Weeks (Shavuot/Pentecost) is the fourth of God's seven appointed feasts, celebrated fifty days after Firstfruits. Israel was commanded to count seven full weeks from the grain offering and then present a new grain offering to the Lord (Leviticus 23:15-16). Uniquely, the two loaves offered at this feast were baked with leaven (Leviticus 23:17), representing sinful humanity being presented to God. This feast was fulfilled in Acts 2 when the Holy Spirit fell upon the disciples on the day of Pentecost, inaugurating the New Covenant church and writing God's law on hearts of flesh rather than tablets of stone.

📖 Key Scripture
• Leviticus 23:15-17 — "You shall count... seven full weeks... you shall present a grain offering of new grain to the LORD."
• Acts 2:1-4 — "When the day of Pentecost arrived... they were all filled with the Holy Spirit."
• Jeremiah 31:33 — "I will put my law within them, and I will write it on their hearts."
⚠️ Modern Corruption
Pentecost is either ignored or reduced to charismatic spectacle.

Most churches either ignore Pentecost entirely or reduce it to an annual commemoration disconnected from its Old Testament roots. The Pentecostal and charismatic movements rightly emphasize the Spirit's work but often divorce Acts 2 from its Levitical context. Meanwhile, cessationists acknowledge the historical event but minimize the Spirit's ongoing power. Both sides miss the typological richness: Pentecost fulfilled Shavuot just as the crucifixion fulfilled Passover. The leavened loaves represent Jew and Gentile -- sinners -- being offered to God through the Spirit. Understanding the feast illuminates the New Covenant.
Usage
• "The Feast of Weeks was fulfilled at Pentecost when God wrote His law not on stone but on the hearts of His people through the Holy Spirit."
• "The two leavened loaves of Shavuot prophetically represented Jew and Gentile -- sinners -- being offered to God as one new humanity in Christ."
