Numbers 6:5-9

LITV(i) 5 All the days of the vow of his separation, a razor shall not pass over his head; he shall be holy until all the days are fulfilled which he has separated to Jehovah. He shall allow the locks of the hair of his head to grow long. 6 All the days of his separation to Jehovah he shall not go near a dead person. 7 He shall not make himself unclean for his father, or for his mother, or for his brother, or for his sister, at their death; because his separation to his God is on his head. 8 All the days of his separation he shall be holy to Jehovah. 9 And of any man dies very suddenly beside him, and he defiles his consecrated head, then he shall shave his head on the day of his cleansing, on the seventh day he shall shave it.
