Peter’s first holy spirit inspired sermon cam to a close. He was speaking to whom? He was addressing the Jews in Jerusalem that came to the feast of Shavuot. The witness was first given and forgiveness offered in Jerusalem as Jesus commanded n Acts 1 :8.

And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:

Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
