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;
Targum Jonathan on Leviticus
Nor unto any person who is dead shall he go in, nor for his father or his mother make himself unclean.
