Numbers 6:3-8

6:3 he must separate himself from wine and strong drink, he must drink neither vinegar made from wine nor vinegar made from strong drink, nor may he drink any juice of grapes, nor eat fresh grapes or raisins. 6:4 All the days of his separation he must not eat anything that is produced by the grapevine, from seed to skin.

6:5 “‘All the days of the vow of his separation no razor may be used on his head until the time is fulfilled for which he separated himself to the Lord. He will be holy, and he must let the locks of hair on his head grow long.

6:6 “‘All the days that he separates himself to the Lord he must not contact a dead body. 6:7 He must not defile himself even for his father or his mother or his brother or his sister if they die, because the separation for his God is on his head. 6:8 All the days of his separation he must be holy to the Lord.
