In the Old Testament Pentecost was the Jewish feast which occurred fifty days after Passover. As the Passover feast celebrated the exodus of the Israelites from the slavery of Egypt, so Pentecost celebrated God’s gift of the ten commandments to Moses on Mount Sinai and the fire that accompanied it. In the New Testament (Acts 2), the Passover event takes on its new meaning as the celebration of Christ’s Death and Resurrection, the “Exodus” of men from this sinful world to the Kingdom of God. And in the New Testament as well, the Pentecostal feast is fulfilled and made new by the coming of the “new law,” the descent of the Holy Spirit upon the disciples of Christ.
