“And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.”
King James Version (KJV)
2:2 And suddenly there came a sound from heaven - So will the Son of man come to judgment. And it filled all the house - That is, all that part of the temple where they were sitting.
Ac 2:2 There came a sound. As this day, the day of the founding of the church, was to be a day of signs and wonders, the shedding forth of the Spirit was made perceptible to all. The sound was heard, the tongues of fire were seen, the word was spoken in many languages. It filled all the house. The mighty sound. At the same time the disciples were filled with the Holy Spirit, their spirits baptized in the Spirit.
