Acts 18:8-11
18:8 Crispus, the president of the synagogue, believed in the Lord together with his entire household, and many of the Corinthians who heard about it believed and were baptized.
18:9 The Lord said to Paul by a vision in the night, “Do not be afraid, but speak and do not be silent,
18:10 because I am with you, and no one will assault you to harm you, because I have many people in this city.”
18:11 So he stayed there a year and six months, teaching the word of God among them.
