1. Setting out on a sea journey · dominant

   All three occurrences place the action within travel by ship. In Acts 15:39 the aorist active infinitive occurs after Barnabas takes Mark, and the APB renders the clause "sailed out to Cyprus"; in Acts 18:18 the imperfect active indicative follows Paul's leave-taking and is rendered "he sailed out toward Syria." In Acts 20:6 the first-person plural aorist active indicative introduces travel from Philippi before the group's arrival at Troas, where the APB renders "We sailed from Philippi."

In the Anselm Project Bible: The APB uses "sailed out" for the journeys toward Cyprus and Syria, and "sailed from" for the departure from Philippi. These phrases confirm the travel setting rather than establish separate meanings.
