OK, I guess I’m not following you. In your first post it seemed to me you were saying the command to receive the Holy Spirit was given while Jesus was here, but that it didn’t occur until Pentecost. I replied that seemed difficult according to the Greek. Then you reply with what I interpret to mean you think there is a time gap between 5 and 6 in Acts, and that they received the Holy Spirit when Jesus was still present. But verse one of Acts makes that a difficult interpretation.
So I think I’m just missing what you are trying to tell me and I would like to understand.
I would put it this way:
Jesus spoke to his disciples on more than one occasion after the resurrection about the Holy Spirit, and their assignment in the kingdom work. On one occasion, he commands them to receive the Holy Spirit, which happened immediately. On another occasion, probably nearer the end, he gives them instructions to wait for the promise of the father before beginning their public ministry. Then he departs and they wait for Pentecost, and then receive the Holy Spirit again.
So perhaps you could correct my timeline to make it agree with what you think occurred, and then we can start discussing from the same starting point.
