1 And when the days of the Pentecost were accomplished, they were all together in one place: 2 And suddenly there came a sound from heaven, as of a mighty wind coming, and it filled the whole house where they were sitting. 3 And there appeared to them parted tongues as it were of fire, and it sat upon every one of them: 4 And they were all filled with the Holy Ghost, and they began to speak with divers tongues, according as the Holy Ghost gave them to speak.
