Parallel
Numbers 6:7
Brenton's English Septuagint · Berean Standard Bible
to his father or his mother, or to his brother or his sister; he shall not defile himself for them, when they have died, because the vow of God is upon him on his head.
Even if his father or mother or brother or sister should die, he is not to defile himself, because the symbol of consecration to his God is upon his head.
