Passage
And when the day of Pentecost was come, they were al with one accord in one place.
And when the day of Pentecost was come, they were al with one accord in one place.
Acts 2:1 And when the day of Pentecost was come, they were al with one accord in one place.
Acts 2:2 And suddenly there came a sounde from heauen, as of a russhing and mightie winde, and it filled all the house where they sate.
Acts 2:3 And there appeared vnto them clouen tongues, like fire, and it sate vpon eche of them.
The verse centers on "pentecost", "come", "accord", and "place". It is saying that the verse draws attention to "pentecost" and "come", so its meaning should be read from those terms before moving to application.
The next verse adds "And suddenly there came a sounde from...", so "pentecost" and "come" should be read forward into that movement. In Acts context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "pentecost" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
