The term refers to a window or opening in a wall, typically used for ventilation, light, or viewing. In the New Testament, it appears in two dramatic contexts: a young man falling from a third-story window during Paul's lengthy discourse in Troas, and Paul himself being lowered in a basket through a window in the Damascus wall to escape arrest. The multilingual evidence consistently points to architectural openings—Spanish ventana, French fenêtre, German Fenster—all capturing the functional aspect of a wall aperture. While classical Greek employed this word for various openings (including embrasures in battlements), the biblical usage remains focused on the architectural sense of a literal window.
