How do we know that when one is unaware engaged in sacrifices, it [the sacrifice] is invalid? Because it says, And he shall kill the bullock before the Lord, [which intimates] that the killing must be for the sake of the bullock. We know this, said he to him, [but] how do we know that [awareness] is indispensable? Ye shall slaughter it with your will, said he, [which teaches,] slaughter it with your knowledge. SINCE THE INTENTION IS DETERMINED ONLY BY THE CELEBRANT. Our Mishnah does not agree with the following Tanna. For it was taught, R. Eleazar son of R. Jose said: I have heard that the owner [of the sacrifice] renders [it] piggul! Raba said: What is R. Eleazar son of R. Jose's reason? Because Scripture says, Then shall he that offereth [his offering] present [unto the Lord etc.] Abaye said: R. Eleazar son of R. Jose, R. Eliezer and R. Simeon b. Eleazar all hold that when one expresses an intention while another performs the act, it is an [effective] intention. R. Eleazar son of R. Jose: this [view] that we have stated. R. Eliezer: as we learnt: If one slaughters for a heathen, his shechitah is fit; but R. Eliezer declares it unfit. R. Simeon b. Eleazar: as it was taught: R. Simeon b. Eleazar stated a general rule: That which is not fit to put away, and such is not [generally] put away, yet it did become fit to a certain person and he did put it away, and then another came and carried it out, the latter is rendered liable through the former's intention. Now, both of them agree with R. Eleazar son of R. Jose: if we say [thus] without, is there a question about within? R. Eleazar son of R. Jose does not agree with the other two: perhaps he ruled thus only [in reference to] within, but not [in reference to] without. R. Simeon b. Eleazar agrees with R. Eliezer: if we say [thus] in connection with the Sabbath, is there a question about idolatry? R. Eleazar does not agree with R. Simeon b. Eleazar: perhaps you rule thus only in connection with idolatry, because it is similar to ‘within’; but in the case of the Sabbath, the Torah interdicted only a considered labour. MISHNAH. WHICH IS THE PLACE [FOR THE RITES] OF SACRIFICES? THE SLAUGHTERING OF SACRIFICES OF THE HIGHER SANCTITY IS AT THE NORTH [SIDE OF THE ALTAR]. THE SLAUGHTERING OF THE BULLOCK AND THE HE-GOAT OF THE DAY OF ATONEMENT IS [DONE] AT THE NORTH, AND THE RECEPTION OF THEIR BLOOD IS [PERFORMED] WITH SERVICE VESSELS AT THE NORTH, AND THEIR BLOOD REQUIRES SPRINKLING BETWEEN THE STAVES [OF THE ARK], ON THE VEIL, AND ON THE GOLDEN ALTAR; [THE OMISSION OF] A SINGLE APPLICATION OF THESE INVALIDATES [THE CEREMONY]. THE RESIDUE OF THE BLOOD HE [THE PRIEST] POURED OUT ON THE WESTERN BASE OF THE OUTER ALTAR, BUT IF HE DID NOT POUR IT OUT, HE DID NOT INVALIDATE [THE SACRIFICE]. AS FOR THE BULLOCKS WHICH WERE BURNT AND THE HE-GOATS WHICH WERE BURNT, THEIR SLAUGHTERING IS [DONE] AT THE NORTH, AND THE RECEPTION OF THEIR BLOOD IS [DONE] AT THE NORTH, AND THEIR BLOOD REQUIRES SPRINKLING BETWEEN THE STAVES [OF THE ARK], ON THE VEIL, AND ON THE GOLDEN ALTAR;ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢᵗᵘᵛ
