Let us recall all of the Jews mentioned in Act 18. Many Jews including newly converted! I think we are on safe ground if we include Pauls inclusion of the Jews in his preaching efforts to....."persuade Jews and Greeks"
Paul in Corinth
1After this Paul
a left Athens and went to Corinth.
2And he found a Jew named Aquila, a native of Pontus, recently come from Italy with his wife Priscilla, because Claudius had commanded all the Jews to leave Rome. And he went to see them,
3and because he was of the same trade he stayed with them and worked, for they were tentmakers by trade.
4And he reasoned in the synagogue every Sabbath, and tried to persuade Jews and Greeks.
5When Silas and Timothy arrived from Macedonia, Paul was occupied with the word, testifying to the Jews that the Christ was Jesus.
6And when they opposed and reviled him, he shook out his garments and said to them, “Your blood be on your own heads! I am innocent. From now on I will go to the Gentiles.”
7And he left there and went to the house of a man named Titius Justus, a worshiper of God. His house was next door to the synagogue.
8Crispus, the ruler of the synagogue, believed in the Lord, together with his entire household. And many of the Corinthians hearing Paul believed and were baptized.
