Sifi: To teach us that the Kohen Tovels his clothes in the same Mikvah that he Tovels himself. 1
Oznayim la'Torah: To teach us that he should not Tovel his clothes in the same Mikvah that he Tovels himself. 2
Why does the Torah need to inform us that the one who burns the Parah is Tamei and requires Kibus Begadim? Why can we not learn it with a Kal va'Chomer from the previous Pasuk from the one who throws the three items into the fire?
