Archaic KJV Word
Shepherd
Modern equivalent: caretaker
What Was Lost
The danger. Ancient Near Eastern shepherding was one of the most dangerous occupations -- wolves, bears, lions, thieves, harsh terrain, and scorching heat. David killed a lion and a bear as a shepherd. 'The Lord is my shepherd' meant 'the Lord is my armed protector who will die fighting before He lets the predators reach me.'
Closest Survivor in Modern English
shepherd (still used but heard as 'gentle caretaker' rather than 'armed protector in hostile wilderness')
Peak Usage (1611)
KJV Psalm 23:1 -- 'The Lord is my shepherd'; John 10:11 -- 'I am the good shepherd'
Died still used but romanticized (~1900)
Hebrew roeh ('one who feeds/tends/rules/leads through dangerous territory') was romanticized into a gentle figure with fluffy sheep in green meadows. The danger, authority, and fierceness of the ancient shepherd was lost.
