レビ記 11:25

וכל הנשא מנבלתם AND WHOSOEVER BEARETH OUGHT OF THE CARRION OF THEM [SHALL BE UNCLEAN UNTIL THE EVEN] — In every passage where there is mentioned uncleanness consequent upon the bearing of anything unclean it is more stringent than uncleanness which is the result of contact, inasmuch as the former requires also the washing of the clothing one happens to wear whilst carrying the unclean thing (Sifra, Shemini, Section 4 8).

וְכׇל־הַנֹּשֵׂ֖א מִנִּבְלָתָ֑ם יְכַבֵּ֥ס בְּגָדָ֖יו וְטָמֵ֥א עַד־הָעָֽרֶב׃

And whoever bears aught of the carcass of them shall wash his clothes, and be unclean until evening.
