Acts 16:30-33

and brought them out and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus, and thou shalt be saved, thou and thy house. And they spake the word of the Lord unto him, with all that were in his house. And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, immediately.
