Torah Temimah: Sifrei — “His clothes” — and not clothes that are already tamei.
English: “His clothes” — and not clothes that are already tamei.
Exclusion of garments that are already impure.
The requirement to wash applies to the ordinary clothes of the handler; clothes that are already tamei (e.g., from tzaraas) are not the subject of this particular command.
