Talmud do Zewachim 3:1

If he removed with his left hand, the disagreement between Rebbi Joḥanan and Jehudah ben Rebbi, since Rebbi Joḥanan said, if a fistful³²Of the flour offering. had been sanctified in a dedicated vessel and he burned it whether out of his hand or out of a vessel, whether by his right hand or by the left. Jehudah ben Rebbi said, either like a purification offering from the hand, or like a reparation offering from a vessel, but only with the right hand³³In Lev. 6:10 it is stated that the flour offering is “most holy, like purification offering and like reparation offering.” For purification offerings it is stated (Lev.4:25, 30, 34) that the Cohen has to apply the blood of the sacrifice with his finger to the corners of the altar. This requirement is missing for the reparation sacrifice (Lev.7:1–7.). They objected: Was it not stated, if he received with his right hand and then put it into his left hand, he must return it to the right hand³⁴Mishnah Zevaḥim 3:1, Zevaḥim 32a, speaking of the blood received in a vessel and brought to the altar to be poured at the wall.? If from the left hand he returns it for the altar, not so much more to the cup? Rebbi La said, if somebody stated this, Rebbi Eleazar ben Rebbi Simeon stated it. As it was stated, it³⁵The fistful taken from a flour offering. does not need sanctification in a cup. Rebbi Eleazar ben Rebbi Simeon follows the argument of his father Rebbi Simeon, as we have stated there³⁶Mishnah Menaḥot3:4., “not in a dedicated vessel it is disqualified, but Rebbi Simeon qualifies it.” How is it? The rabbis who require a dedicated vessel need the right hand³⁷Menaḥot26b.; Rebbi Simeon [who] does not require a dedicated vessel does not need the right hand. Rebbi Mana said, I am wondering how the rabbis could compare the removal of ashes to burning, but it can be compared only to the lifting of the fistful, since both are by lifting³⁸Since everybody agrees that at all places where the verse requires that the action be done by a Cohen he must use his right hand; therefor the lifting of the fistful must be with the Cohen’s right hand..
