Numbers 6:7-12
English Standard Version
Chapter 6
7Not 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. 8All the days of his separation he is holy to the Lord.
9"And if 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.
10On the eighth day he shall bring two turtledoves or two pigeons to the priest to the entrance of the tent of meeting,
11and the priest shall offer one for a sin offering and the other for a burnt offering, and make atonement for him, because he sinned by reason of the dead body. And he shall consecrate his head that same day
12and separate himself to the Lord for the days of his separation and bring a male lamb a year old for a guilt offering. But the previous period shall be void, because his separation was defiled.
