Numbers 6:5-9

VIN(i) 5 All the time of his separation no razor shall pass over his head, until the day be fulfilled of his consecration to the Lord. He shall be holy, and shall let the hair of his head grow. 6 All the days of his separation to the LORD he shall not go near a dead person. 7 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. 8 All the days of his separation he is holy to the LORD. 9 "If any man dies very suddenly beside him, and he defiles the head of his separation; then he shall shave his head in the day of his cleansing. On the seventh day he shall shave it.
