Numbers 6:7

לְאָבִ֣יו וּלְאִמּ֗וֹ לְאָחִיו֙ וּלְאַ֣חֹת֔וֹ לֹא־יִטַּמָּ֥א לָהֶ֖ם בְּמֹתָ֑ם כִּ֛י נֵ֥זֶר אֱלֹהָ֖יו עַל־רֹאשֽׁוֹ׃

ἐπὶ πατρὶ καὶ ἐπὶ μητρὶ καὶ ἐπ’ ἀδελφῷ καὶ ἐπ’ ἀδελφῇ, οὐ μίαν θήσεται ἐπ’ αὐτοῖς ἀποθανόντων αὐτῶν, ὅτι εὐχὴ θεοῦ αὐτοῦ ἐπ’ αὐτῷ ἐπὶ κεφαλῆς αὐτοῦ·

Por su padre, ni por su madre, por su hermano, ni por su hermana, no se contaminará con ellos cuando murieren; porque consagración de su Dios tiene sobre su cabeza.

Even if his father or mother or brother or sister should die, he is not to defile himself, because the crown of consecration to his God is upon his head.
