What does the Bible say about the Feast of Pentecost?

The Feast of Pentecost is outlined in Leviticus 23:15-22, where the Israelites were commanded to celebrate it by offering the first fruits of their harvest. This feast occurs after they count seven weeks or 49 days from the Feast of First Fruits, culminating in the 50th day of celebration. It commemorates God's provision and the beginning of the wheat harvest, which was a significant agricultural milestone for the community. During this feast, two wave loaves made from fine flour were presented before the Lord, symbolizing both gratitude and recognition that the harvest is a blessing from God. Importantly, this feast is also linked to the outpouring of the Holy Spirit on the day of Pentecost as recorded in Acts 2, marking the birth of the Church and the inclusion of both Jew and Gentile into one body of Christ.
