Paul's commission was not to the Jews.....why would he be preaching to them?
"But when [Paul and his party] departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the Sabbath day and sat down. " (Acts 13:14)
"Now it happened in Iconium that [Paul and Barnabas] went together to the synagogue of the Jews, and so spoke that a great multitude both of the Jews and of the Greeks believed. " (Acts 14:1)
"Then Paul, as his custom was, went in to them, and for three Sabbaths reasoned with them from the Scriptures, ... Then the brethren immediately sent Paul and Silas away by night to Berea. When they arrived, they went into the synagogue of the Jews." (Acts 17:2,10)
"And [Paul] reasoned in the synagogue every Sabbath, and persuaded both Jews and Greeks." (Acts 18:4)
"And [Paul] came to Ephesus, and left them there; but he himself entered the synagogue and reasoned with the Jews." (Acts 18:17)
"And [Paul] went into the synagogue and spoke boldly for three months, reasoning and persuading concerning the things of the kingdom of God." (Acts 19:8)
Take it up with Paul. In every place he would first go to the Jews in their synagogue, and then, when he was rejected, he would go to the gentiles. No doubt this provoked the Jews to even more animus against Paul.
