Answer:
1) on the day of Pentecost
2) At the beautiful gate
3) in the house of Cornelius
4) At the Jerusalem council
Explanation:
On the day of Pentecost when the Holy Spirit descended on the apostles, Peter was the one among the twelve who rose up and addressed the crowd that gathered in Jerusalem at the event.
At the beautiful gate when the lame man was healed, Peter again gave another sermon that converted thousands of Jews to the faith.
After Peter received the vision about unclean animals , he followed the delegates from Cornelius to his house and there he preached a message in which many gentiles were converted as well as also received the Holy Spirit.
Lastly, at the Jerusalem council, Peter defended the fact that the gentiles not only believed but have also received the gift of the Holy Spirit.
