This verb means to act piously, show reverence toward God, or discharge religious duties. In Acts 17:23, Paul observes that Athenians are 'very religious' or carefully reverent in all things—even worshiping an unknown god to avoid offending any deity. In 1 Timothy 5:4, widows with children or grandchildren should learn to 'show godliness to their own household'—practicing piety through caring for family. The multilingual evidence shows religious devotion: Spanish 'adoráis/honrar piadosamente' (you worship/to honor piously), French 'être pieux' (to be pious). Classical usage included outward acts of service toward gods; biblical usage extends to family care as religious duty.
