And in respect of peace-offerings [this is derived] from the expression ‘there’ stated [in connection with peace-offerings] and also in connection with the Second Tithe. Then it follows, as peace-offerings are not brought from actual Second Tithe produce. so the [bread of the] thank-offering may not be brought from actual Second Tithe produce; and wheat bought with Second Tithe money is not actual Second Tithe produce. And I will state my reason: Whence do I know this of the thank-offering? From peace-offerings. And in respect of peace-offerings [this is derived] from the expression ‘there’ stated [in connection with peace-offerings] and also in connection with the Second Tithe. Then it follows, as peace-offerings are not of the same kind as Second Tithe, so the [bread of the] thank-offering may not be from that which is the same kind as Second Tithe; thus excluding wheat bought from Second Tithe money which is the same kind as Second Tithe. R. Ammi said, If a man designated Second Tithe money for a peace-offering, the peace-offering has not appropriated it. Why? Because the sanctity of the peace-offering is not so potent that it can be imposed upon the sanctity of Second Tithe. An objection was raised: If a man bought a wild animal for a peace-offering or cattle for use as ordinary food, the hide does not become unhallowed. Does not this prove that the peaceoffering has appropriated it? — Surely it has been stated in connection with this that Rab said, The peace-offering has not appropriated it; and what is meant by ‘the hide does not become unhallowed’? It means this:-[The wild animal] does not come within the category [of peace-offerings] for its hide to become unhallowed. And why is it so? — Rabbah answered. It is as if he bought an ox for ploughing. It was stated: If a man designated Second Tithe money for a peace-offering, R. Johanan said, [The peace-offering] has appropriated it; R. Eleazar said, It has not appropriated it. According to R. Judah who maintains that the [Second] Tithe is secular property they both agree that the peace-offering has appropriated it; they differ only according to R. Meir who maintains that the [Second] Tithe is sacred property. He who said that it has not appropriated it is in accord with R. Meir; but he who said that it has appropriated it is of the opinion that since Second Tithe is usually offered as peace-offerings, if a man designates [Second Tithe money for a peace-offering] the designation is binding. An objection was raised: If a man designated Second Tithe money for a peace-offering, when he redeems it he must add two fifths, one in respect of things consecrated and one in respect of Second Tithe! — Do you think that this teaching is the opinion of all? It is only the opinion of R. Judah. MISHNAH. WHENCE [IS IT DERIVED]THAT IF A MAN SAYS,’I TAKE UPON MYSELF [TO OFFER] A THANK-OFFERING’, HE MAY BRING IT ONLY FROM WHAT IS UNCONSECRATED? BECAUSE IT IS WRITTEN, AND THOU SHALT SACRIFICE THE PASSOVER-OFFERING UNTO THE LORD THY GOD OF THE FLOCK AND THE HERD. BUT IS NOT THE PASSOVER-OFFERING BROUGHT ONLY FROM THE LAMBS AND FROM THE GOATS? WHY THEN IS IT WRITTEN, OF THE FLOCK AND THE HERD? IT IS TO COMPARE WHATSOEVER IS BROUGHT FROM THE FLOCK AND THE HERD WITH THE PASSOVER-OFFERING: AS THE PASSOVER-OFFERING IS OBLIGATORY AND OFFERED ONLY FROM WHAT IS UNCONSECRATED, SO EVERYTHING THAT IS OBLIGATORY MAY BE OFFERED ONLY FROM WHAT IS UNCONSECRATED. THEREFORE IF A MAN SAYS, ‘I TAKE UPON MYSELF [TO OFFER] A THANK-OFFERING’, OR ‘I TAKE UPON MYSELF [TO OFFER] A PEACE-OFFERING’, SINCE THESE ARE OBLIGATORY THEY MAY BE OFFERED ONLY FROM WHAT IS UNCONSECRATED. THE DRINK-OFFERINGS IN EVERY CASE MAY BE OFFERED ONLY FROM WHAT IS UNCONSECRATED. GEMARA. And whence do we know it for the Passover-offering itself? — It was taught: R. Eliezer said: A Passover-offering was ordained to be brought in Egypt and a Passover-offering was ordained for later generations; as the Passover-offering that was ordained in Egypt could be brought only from what was unconsecrated, so the Passover-offering that was ordained for later generations may be brought only from what is unconsecrated. Said to him R. Akiba, Is it right to infer the possible from the impossible? The other replied, Although it was impossible [otherwise]. it is nevertheless a striking argument and we may make an inference from it. Then R. Akiba put forward the following argument [in refutation]: This was so of the Passover-offering ordained in Egypt since it did not require the sprinkling of blood and the offering of the sacrificial portions upon the altar; 33ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢᵗᵘᵛʷˣʸᶻᵃᵃᵃᵇᵃᶜᵃᵈᵃᵉᵃᶠᵃᵍ
