Shimshon's nazirite status is unique and peculiar. The nazir is by definition a person who is profoundly driven towards an encounter with the Divine. Shimshon's status is imposed upon him by Divine command from birth and not by choice. Just like the Hazal describe the Nazir as a reaction to the Sotah - the breakdown of the relationship between a husband and wife - so too God's command of coerced Nazirite status upon Shimshon is a reaction to the complete adoption of the immoral Cannanite lifestyle by the nation by the end of the Book of Judges.
