1The day of Pentecost came. The believers all gathered in one place. 2Suddenly a sound came from heaven. It was like a strong wind blowing. It filled the whole house where they were sitting. 3They saw something that looked like tongues of fire. The flames separated and settled on each of them. 4All of them were filled with the Holy Spirit. They began to speak in languages they had not known before. The Spirit gave them the ability to do this.
