5At that time many Jews were staying in Jerusalem to celebrate the Pentecost festival. They were people who always tried to obey the Jewish laws. They had come from many different HYP countries.
6When they heard that loud noise like a wind, a crowd came together to the place where the believers were. The crowd ◄was amazed/did not know what to think►, because each of them was hearing one of the believers speaking in that person's own language.
