Emor 21-03.ViLaachoso HaBisula (5773/2013). The dinim of Khuna that prohibit a Kohein from becoming Tamai (spiritual contamination) has seven exceptions: Father, Mother, Son, Daughter, wife, brother and… (in a separate Posuk) sister. Why is the sister in a separate Posuk and why are there three different rules that narrow what kind of sister one is permirtted (and obligated) to become tamai for? This class includes Rashi, E. Ezra, Abarbanel, Toras Kohanim, Reb Yonasan Aibeshitz and a Ma’amar (5724). In the Ma’amar this is linked to Hashem becoming Tamai to save all types of Jews: 1) Tzadik, 2) Baal T’shuva, 3) One who is still not a Baal T’shuva.
