The word comes from the Greek which means fifty. So, Pentecost was a celebration on the fiftieth day after Passover. It was a culmination of the feast of weeks (Exodus 34:22, 23). Pentecost in the New Testament is the arrival of the Holy Spirit for the church (Acts 2). At Pentecost the disciples of Jesus were gathered; and upon the filling of the Holy Spirit, they heard a great wind and spoke in tongues as tongues of fire that settled upon them. The significance of the fire can be found in recognizing it as a symbol of the dwelling of the Spirit of God (Exodus 19:18; 1 Pet. 4:14).
