Archaic KJV Word
Glory
Modern equivalent: splendor
What Was Lost
The physical weight of divine presence. In Hebrew, kavod meant 'heavy' -- God's glory was so substantial it could fill the temple like smoke, drive priests to their knees, and kill those who approached unworthily. Glory was not pretty light but crushing, terrifying, magnificent reality.
Closest Survivor in Modern English
glory (still used but emptied -- 'morning glory' is a flower, 'glory days' means nostalgia)
Peak Usage (1611)
KJV Exodus 33:18 -- 'Show me thy glory'; John 1:14 -- 'we beheld his glory'
Died still used but diluted (~1950)
Reduced from kavod ('weight/heaviness/substance') and doxa ('radiant manifestation of character') to vague 'brightness' or 'fame,' losing both the Hebrew weight and the Greek radiance.
What Replaced It
“brightness”
Visual only; glory was the total overwhelming manifestation of God's character -- terrifying, beautiful, and heavy
“splendor”
Aesthetic only; glory in Hebrew literally meant 'heaviness' -- the crushing weight of God's presence
“fame”
Human-centered; glory was the objective reality of who God is, not reputation
