Acts 2:1-6 CSB
When the day of Pentecost had arrived, they were all together in one place. Suddenly a sound like that of a violent rushing wind came from heaven, and it filled the whole house where they were staying. They saw tongues like flames of fire that separated and rested on each one of them. Then they were all filled with the Holy Spirit and began to speak in different tongues, as the Spirit enabled them.
Now there were Jews staying in Jerusalem, devout people from every nation under heaven. When this sound occurred, a crowd came together and was confused because each one heard them speaking in his own language.
