Acts 18:8-11

And Crispus, the ruler of the synagogue, believed in the Lord with all his house; and many of the Corinthians hearing believed, and were baptized. And the Lord said unto Paul in the night by a vision, Be not afraid, but speak and hold not thy peace: for I am with thee, and no man shall set on thee to harm thee: for I have much people in this city. And he dwelt there a year and six months, teaching the word of God among them.
