A STADE — a Greek unit of about 185 metres, some 600 feet, and also the racecourse of that length (whence the English 'stadium'; 1 Corinthians 9:24 uses it that way). ⚠ Revelation 21:16 measures the city at TWELVE THOUSAND stadia in each direction — about 1,400 miles or 2,200 km — which is not a survey but 12 x 1,000, matching the 144 (12 x 12) cubits of wall in the next verse. KJV and ASV print 'furlongs', a live English unit in 1611 and now a horse-racing term. → first discussed at Rev 21:16
