Acts 27:14 describes the violent northeaster wind called Euroclydon or Euraquilo that shipwrecked Paul's vessel. The adjective emphasizes the wind's typhoon-like violence and danger. This tempestuous storm drove the ship helplessly for many days, threatening all aboard with death. Luke's detailed account of the storm demonstrates both nautical knowledge and theological purpose—even natural forces serve God's plan, as the shipwreck ultimately brings Paul to Rome and provides opportunities for witness. The term captures the terrifying power of Mediterranean winter storms.
