וְעַ֛ל כָּל־נַפְשֹׁ֥ת מֵ֖ת לֹ֣א יָבֹ֑א לְאָבִ֥יו וּלְאִמּ֖וֹ לֹ֥א יִטַּמָּֽא׃
neither shall he go in to any dead body, nor defile himself for his father, or for his mother;
Shenei Luchot HaBerit
Commandment 376 forbids the Nazirite to remain under the same roof as a dead human being; the Torah says: "ועל כל נפשות מת לא יבא" (Leviticus 21,11).
