Lamentations 4:7-8 describes the reversal of fortune among some group of people. The NIV has:
Their princes were brighter than snow and whiter than milk
While the KJV has:
Her Nazarites were purer than snow, they were whiter than milk
These are— to my mind— two very different groups of people. As far as I can tell, there isn't a textual issue here with the KJV following a different text. So which is the appropriate translation?
