This noun denotes a festal assembly or joyful public gathering, typically for religious celebration. Hebrews uses it to describe the heavenly assembly of the firstborn enrolled in heaven. Classical Greek employed the term for national festivals honoring the gods, particularly events combining worship and celebration. The word evokes joy, solemnity, and corporate worship—not merely a meeting but a festive occasion. In Hebrews, it paints the heavenly reality believers have already joined.
