Acts 18:4-6

4Every Sabbath he reasoned in the synagogue, trying to persuade Jews and Greeks alike. 5And when Silas and Timothy came down from Macedonia, Paul devoted himself fully to the word, testifying to the Jews that Jesus is the Christ. 6But when they opposed and insulted him, he shook out his garments and told them, “Your blood be on your own heads! I am innocent of it. From now on I will go to the Gentiles.”
