They were all filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. This account in Acts 2 shows the early church experiencing and proclaiming in various tongues under the Spirit's presence. The text reflects the real-life situation while being organized into four paragraphs for reader comprehension. The first paragraph introduces the background of the event, the second describes the phenomenon of speaking in tongues, the third discusses the reactions of the apostles and the church community, and the fourth presents applications and implications for believers today.
