Acts 18:4-8

And Paul was reasoning in the synagogue every Sabbath and trying to persuade Jews and Greeks.

But when Silas and Timothy came down from Macedonia, Paul began devoting himself completely to the word, testifying to the Jews that Jesus was the Christ.

But when they resisted and blasphemed, he shook out his garments and said to them, “Your blood is on your own heads! I am clean. From now on I will go to the Gentiles.”

Then he left the synagogue and went to the house of a man named Titius Justus, a worshiper of God, whose house was next door to the synagogue.

Crispus, the leader of the synagogue, believed in the Lord together with his entire household; and many of the Corinthians, as they listened to Paul, were believing and being baptized.
