The Hebrew verb nazar means to separate, to consecrate, to dedicate, or to abstain. It is the root of the word "Nazirite" (nazir, H5139) and describes the act of setting oneself apart for sacred purposes. The separation involves both abstaining from certain things (wine, unclean contact) and being dedicated to God for special service.
The Nazirite vow (Numbers 6) represents one of the most intense forms of personal devotion in the Old Testament. By choosing to separate themselves to the LORD, individuals voluntarily took on restrictions that symbolized total consecration. Famous Nazirites include Samson and Samuel. The concept reveals that holiness fundamentally means being set apart — not merely moral purity but purposeful dedication to God's service.
