Until what event did the early Jewish believers preach the word only to Jews?
The early Jewish believers preached the Word only to Jews until Saul's conversion. Acts 11:19 describes them as scattered from Saul's persecution and preaching to none but Jews, with the stoning of Stephen, seven years after Pentecost, as a late example before Saul's conversion.
Les teaches that Acts 11:19 confirms the Jewish believers, scattered by Saul's persecution, went throughout that area preaching the Word to none but Jews, all the way up to Saul's conversion. He points out that as late as the stoning of Stephen—seven years after Pentecost—they still preached only to Jews. Since they did not yet have the New Testament, they used the Old Testament. Les emphasizes that God was dealing only with the Jew during this period, and he references Ephesians chapter 2. He hopes his listeners will not turn away from this teaching as some turned away from Jesus' words in John's Gospel about drinking His blood and eating His flesh.
Now they which were scattered abroad upon the persecution that arose about Stephen travelled as far as Phenice, and Cyprus, and Antioch, preaching the word to none but unto the Jews only.
