Atos 13:42

And as they went out, they besought that these words might be spoken to them the next sabbath. Now when the synagogue broke up, many of the Jews and of the devout proselytes followed Paul and Barnabas; who, speaking to them, urged them to continue in the grace of God.

So far, so good. Paul's great sermon had fully captured the attention of many who were inclined to accept Christianity, and the conversations regarding this continued, apparently, throughout the whole day. An appointment was made for Paul to speak again in that same synagogue on the sabbath day a week later. In the meantime, how- ever, Satan would stir up opposition to the truth.
