1)[line 2]וליטמא לוV'LITAMEI LO
The Torah (Vayikra 21:1-4) forbids Kohanim from coming into contact with dead bodies while commanding them to come into contact with certain deceased relatives. Those relatives are his mother, father, son, daughter, brother, unmarried virgin sister from his father, and permitted wife.
2)[line 5]"לא יטמא בעל בעמיו להחלו""LO YITAMA BA'AL B'AMAV L'HEICHALO"- "A husband may not defile himself for his wife whose marriage profanes him." (Vayikra 21:4)
3)[line 26]רבי יוסי בן יהודה אומר אינו חייב אלא משום אחותו בלבדREBBI YOSI BEN YEHUDAH OMER, EINO CHAYAV ELA MISHUM ACHOSO BILVAD- that is, according to Rebbi Yosi ben Yehudah, the second verse ("Bas Eshes Avicha") was not written as a negative prohibition at all. Rather, it was written to limit the prohibition of "Achoso" only to certain sisters (as the Gemara concludes later on this page)
4)[line 38]שאין מזהירין מן הדיןEIN MAZHIRIN MIN HA'DIN
(a)One who commits an action that the Torah warns ("Azharah") is prohibited (a Lav) is liable to receive Malkus (lashes). Other prohibitions are more stringent, and are punishable by the death penalty. Certain types of prohibitions, however, are not punishable by Malkus or the death penalty. One precondition to these penalties is that the Azharah be clearly spelled out in the Torah (Yoma 81a).
(b)In a Beraisa found in the introduction to the Sifra (the Halachic Midrash on Vayikra), Rebbi Yishmael lists the thirteen methodologies employed by Chazal when determining Halachah from the verses of the Torah. One of these is Kal va'Chomer (an a fortiori argument), also referred to as a "Din." Should it be determined through a Kal va'Chomer that a certain action must be prohibited, it is indeed forbidden. However, one cannot receive punishment for transgressing such a prohibition, since the Torah did not forbid it directly.
