1 Now when the day of Pentecost had come, they were all together in one place.2 Suddenly a sound like a violent wind blowing came from heaven and filled the entire house where they were sitting.3 And tongues spreading out like a fire appeared to them and came to rest on each one of them.4 All of them were filled with the Holy Spirit, and they began to speak in other languages as the Spirit enabled them.
- The events occur on Pentecost, a major Jewish festival celebrating the wheat harvest and the giving of the Law at Sinai, fifty days after Passover.
- "All together in one place" likely refers to the core group of about 120 believers mentioned in Acts 1:15.
- The sound like wind and tongues like fire are audible and visible manifestations symbolizing the powerful, purifying presence of the Holy Spirit, reminiscent of God's presence at Sinai (Exodus 19).
- "Tongues" (Greek: *glōssai*) here refers to known languages, as indicated by the reaction in verses 6-11.
- Being "filled with the Holy Spirit" signifies empowerment for service and witness, fulfilling Jesus' promise in Acts 1:8.
- This event marks the birth of the Church as the Spirit-empowered community of Christ.
- The miracle of speaking in other languages serves as an initial sign of the gospel breaking down ethnic and linguistic barriers, a reversal of the confusion at Babel (Genesis 11).
- The Spirit rests on *each one*, indicating a universal endowment for all believers present, not just the apostles.
