Numbers 6:8

Touching dead bodies made people ceremonially unclean (9:6–10). Priests could only touch the dead bodies of close relatives (Leviticus 21:1–4). But Nazirites could not touch any dead body at all.

The voluntary vow of a Nazirite allowed men or women to separate themselves to the LORD. The Nazirite lifestyle varied throughout Hebrew history. People took vows seriously in ancient times as a way to show devotion or gratitude to God. This vow could be temporary or permanent. It involved avoiding alcoholic drinks, not cutting hair, and avoiding contact with corpses.

Nazirite restrictions allowed members of non-Levitical tribes to have a more demanding and highly respected relationship with God. The Nazirite vow is probably best known because of Samson (Judges 13–16). See also 1 Samuel 1:11; Jeremiah 35; Acts 18:18; 21:23–26; compare Luke 1:15.
