Matthew Poole and continuators on Lamentations 4:7

7 Her Nazarites were purer then snow, they were whiter then milk, they were more ruddy in body then rubies, their polishing was of sapphire .

By Nazarites in this place the most and best interpreters do not understand persons, who were of the Religious order of Nazarites, the Laws of which order are to be read, Numb. 6.2. and of whom we read Amos 2.11, 12. for here is a beauty described (under several metaphors) which could never agree to them: but persons that were nobly and ingenuously bred. The word Nezer signifying a crown, or Ensign of honour, 2 Sam. 1.10. 2 Kings 11.12. The name Nazarite was given to persons splendid for their breeding, and education or honour and dignity, it is given to Ioseph, Gen. 49.26. we translate it separate from his Brethren, Deut. 33.16. so Na[illegible: 1 letter]um 3.17. Her Nazarites in this place signifieth her separated ones, who either in respect of birth, education, estate, places of Magistracy or the like, were distinguished from the rest of the people.

He expresseth their former splendid estate by the Metaphors of Snow, Milk, Rubies and Sapphires.
