Ma`asei (Acts) 2:1-4

And when the Day of the Festival of Shaḇu‛ot had come, they were all with one mind in one place. And suddenly there came a sound from the heaven, as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared to them divided tongues, as of fire, and settled on each one of them. And they were all filled with the Set-apart Spirit and began to speak with other tongues, as the Spirit gave them to speak.
