'Separation' in the Bible

All the days of his separation you will not eat from anything that is made from the grapevine, from sour grapes to the skin [of grapes].

" 'All the days of the vow of his separation a razor will not pass over his head. Until fulfilling the days that he separated himself to Yahweh he will be holy and grow long the locks of the hair of his head.

for even his father, mother, brother, or sister he will not make himself unclean {by their death}, because the separation to his God [is] on his head.

He will be holy for Yahweh all the days of his separation.

" 'If someone dies suddenly and makes the head of his separation unclean, he will shave off [the hair of] his head on the day of his cleansing; on the seventh day he will shave it off.

He will rededicate to Yahweh the days of his separation and bring a ram-lamb {in its first year} as a guilt offering. The former days [of his vow] will fall away because his separation was defiled.

" 'This [is] the regulation of the Nazirite for the day of the fulfilling of the days of his separation: one will bring him to the doorway of the tent of the assembly.

" 'This is the regulation of the Nazirite who has made a vow of his offering to Yahweh according to his separation, {in addition to what he can afford}. In accordance to the word of his vow that he vowed, he will do, concerning the instruction of his separation.'"
