The document describes three biblical accounts from Acts where speaking in tongues occurred. In Acts 2, the disciples heard a sound like wind and saw tongues of fire before speaking in tongues. In Acts 8, Samaritans spoke in tongues after Peter and John prayed for them. In Acts 10, Gentiles spoke in tongues and praised God after listening to Peter's preaching. The document notes that speaking in tongues was sometimes accompanied by sounds, sights, tongues, praise, or prophecy and involved waiting, praying, preaching or teaching with Jews, Samaritans and Gentiles all experiencing it.
