Numbers 6:4

²Speak to the children of Israel, and thou shalt say to them, Whatsoever man or woman shall specially vow a vow to separate oneself with purity to the Lord,

³he shall purely abstain from wine and strong drink; and he shall drink no vinegar of wine or vinegar of strong drink; and whatever is made of the grape he shall not drink; neither shall he eat fresh grapes or raisins,

— Numbers 6:4 —

⁵all the days of his separation—a razor shall not come upon his head, until the days be fulfilled which he vowed to the Lord: he shall be holy, cherishing the long hair of the head,

⁶all the days of his vow to the Lord: he shall not come nigh to any dead body,
