Parallel
Numbers 6:7
Westminster Leningrad Codex · Berean Standard Bible
לְאָבִ֣יו וּלְאִמּ֗וֹ לְאָחִיו֙ וּלְאַ֣חֹת֔וֹ לֹא־ יִטַּמָּ֥א לָהֶ֖ם בְּמֹתָ֑ם כִּ֛י נֵ֥זֶר אֱלֹהָ֖יו עַל־ רֹאשֽׁוֹ׃
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.
