Acts 18:4-6

4He addressed both Jews and Greeks in the synagogue every Sabbath, attempting to persuade them.

5Now when Silas and Timothy arrived from Macedonia, Paul became wholly absorbed with proclaiming the word, testifying to the Jews that Jesus was the Christ.

6When they opposed him and reviled him, he protested by shaking out his clothes and said to them, “Your blood be on your own heads! I am guiltless! From now on I will go to the Gentiles!”
