Who did Peter address in the early chapters of Acts?

In the early chapters of Acts, Peter addressed the children of Israel and the men of Israel. He pleaded with them to respond to the truth that the one they had crucified was their Messiah. Israel as a nation largely rejected that message, though some believed.

Les teaches that even after the crucifixion, when you come into the early chapters of Acts, Peter addresses the people as “oh, ye children of Israel, ye men of Israel.” Peter pleads with them to respond to the fact that the one they crucified was their Messiah. But Israel would not believe it nationally; some did, but for the most part, the nation rejected it. This shows God was still dealing with Israel in that early Acts period.

Acts 2

Was Peter preaching to Jews or Gentiles in Acts 2?

Peter was preaching to Jews in Acts 2. The setting was the Jewish Feast of Pentecost, with Jews from all over the then-known world gathered in the temple area. The speaker was Jewish, the audience was Jewish, and the message was Jewish; Gentiles are not mentioned in this context.
