Numbers 6:5-7

5All the days of his vow of separation, no arazor shall touch his head. Until the time is completed for which he separates himself to the Lord, he shall be holy. bHe shall let the locks of hair of his head grow long.

6All the days that he separates himself to the Lord che shall not go near a dead body. 7 dNot even for his father or for his mother, for brother or sister, if they die, shall he make himself unclean, because his separation to God is on his head.
