Negaim 14:8 - 14:9

וסמך שתי ידיו עליו – but prior to laying his hands upon it, it requires waving, for the guilt offering of a leper requires waving/shaking it live (see Leviticus 14:24: “The priest shall take the lamb of reparation offering – i.e., the guilt offering – and the LOG of oil, and elevate them as an elevation offering before the LORD"/"והניף אתם הכהן תנופה לפני ה'" ).

ואחד ביד – as it is written (Leviticus 14:14): “The priest shall take some of the blood of the reparation offering (i.e., the guilt offering) and the priest shall put it on the ridge of the right ear of him who is being purified l[and on the thumb of his right hand, and on the big toe of his right foot].” Just as the placing is done by the Kohen’s essence himself, even the receiving [of the blood] is done by the Kohen essence himself.

אינו צריך טבילה – for he had already immersed the previous evening, as it is written (Leviticus 14:9): “On the seventh day he shall shave off all his hair…he shall wash his clothes and bathe his body in water.” But the Sages state, for since he is likely to [be susceptible for] uncleanness, lest he did not guard himself properly in purity and became defiled after he immersed [in a Mikveh], therefore he requires another immersion from doubt. But the Halakha is according to the Sages.

הכניס ראשו (he put his head inside) – because someone who requires a ceremony of atonement does not enter in the Israelite courtyard, and the blood of the guilt-offering (i.e., reparation offering) was invalidated by leaving if he went outside of the courtyard, therefore, the leper would stand in the Gate of Nikanor which was between the Courtyard of the Women and the Courtyard of the Israelites, but he puts his head inside the courtyard until they place the gifts on his earlobe, and he puts his hand and foot in until he (i.e., the Kohen) places it (i.e., the blood) on his right thumb and right big-toe.

תנוך (the ridge) – this is the middle partition of an ear.

רבי יהודה אומר וכו' – but the Halakha is not according to Rabbi Yehuda.

אין לו טהרה עולמית – for we require as it is written in Scripture. And especially that his ear was lopped off/mutilated or his [right] thumbs/big toes after they were made dependent upon purification.

רבי אליעזר אומר נותן הוא על מקומו (Rabbi Eliezer states: He puts It (i.e., the blood) on their place) – for we don’t require it as it is written in Scripture. But the Halakha is not according to Rabi Eliezer. And similarly, the Halakha is not according to Rabbi Shimon who stated that if he put it on his left [thumb and left toe] he has fulfilled his obligation.
