Numbers 6:2-7

2“Give the following instructions to the people of Israel. “If any of the people, either men or women, take the special vow of a Nazirite, setting themselves apart to the Lord in a special way,

3they must give up wine and other alcoholic drinks. They must not use vinegar made from wine or from other alcoholic drinks, they must not drink fresh grape juice, and they must not eat grapes or raisins.

4As long as they are bound by their Nazirite vow, they are not allowed to eat or drink anything that comes from a grapevine—not even the grape seeds or skins.

5“They must never cut their hair throughout the time of their vow, for they are holy and set apart to the Lord. Until the time of their vow has been fulfilled, they must let their hair grow long.

6And they must not go near a dead body during the entire period of their vow to the Lord.

7Even if the dead person is their own father, mother, brother, or sister, they must not defile themselves, for the hair on their head is the symbol of their separation to God.
