American Standard Version (ASV):
He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die; because his separation unto God is upon his head.
King James Version (KJV):
He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God [is] upon his head.
