acts 27:9 Now when much time was spent, and when sailing was now dangerous, because the fast was now already past, Paul admonished them, - Free Bible Online

      9, 10. when much time was spent--since leaving Cæsarea. But for unforeseen delays they might have reached the Italian coast before the stormy season.
      and when sailing--the navigation of the open sea.
      was now dangerous, because the fast was now . . . past--that of the day of atonement, answering to the end of September and beginning of October, about which time the navigation is pronounced unsafe by writers of authority. Since all hope of completing the voyage during that season was abandoned, the question next was, whether they should winter at Fair Havens, or move to Port Phenice, a harbor about forty miles to the westward. Paul assisted at the consultation and strongly urged them to winter where they were.
