Acts 18:7-8

He entered into a man's house, named Justus A Gentile, but a worshipper of the true God: and he preached there, though probably he still lodged with Aquila. He the rather chose to preach in the house of this religious proselyte, because, as it was near the synagogue, such of the Jews as were of a teachable disposition, had thereby an opportunity of hearing him. Accordingly, when he preached in this house, Crispus, the chief ruler of the synagogue, believed Whom Paul baptized; with all his house. And many of the Corinthians The formerly idolatrous inhabitants of the city; hearing The conversion of Crispus, and the preaching of Paul; believed and were baptized Namely, by Silas and Timothy; for the apostle affirms that he baptized none of the Corinthians but Crispus and Gaius, and the household of Stephanus, 1 Corinthians 1:14; 1 Corinthians 1:16.
