Shabbat

Yet the law is as none of these rulings, but as R. Joshua b. Levi's dictum: When the Day of Atonement falls on the Sabbath, he who recites the Ne'ilah Service  must refer to the Sabbath:  it is a day when four services are obligatory.  Then one law contradicts another! [First] you say that the law is as R. Joshua b. Levi, whereas it is an established principle that the law is as Raba. For Raba said: On a Festival that falls on the Sabbath, the Reader  who descends before the desk  at the Evening Service  need not make mention of the Festival,  since but for the Sabbath the Reader would not descend [before the desk] at the Evening Service on Festivals. — How compare! There, by ritual law it is not required even on the Sabbath,  and it was the Rabbis who instituted it on account of danger;  but here it is a day when four services are a [statutory] obligation. NOR WITH TAIL FAT etc. But the SAGES are identical with the first Tanna? — They differ in respect to R. Beruna's dictum in Rab's name,  but it is not clearly defined. MISHNAH. ONE MAY NOT KINDLE [THE SABBATH LAMP] WITH OIL OF BURNING ON FESTIVALS.  R. ISHMAEL SAID: ONE MAY NOT LIGHT [IT] WITH 'ITRAN,  FOR THE HONOUR OF THE SABBATH; BUT THE SAGES PERMIT IT WITH ALL OILS; WITH SESAME OIL, NUT OIL, RADISH OIL, FISH OIL, GOURD OIL, ITRAN AND NAPHTHA. R. TARFON SAID: ONE MAY LIGHT [IT] WITH OLIVE OIL, ONLY. GEMARA. What is the reason? — Because sacred [commodities] may not be burnt on Festivals.  Whence do we know it? — Said Hezekiah, and the School of Hezekiah taught likewise: And ye shall let nothing of it remain until the morning; but that which remaineth of it until the morning [ye shall burn with fire]:  now [the second] until the morning' need not be stated. What then is the teaching of, until the morning'? Scripture comes to appoint the second morning for its burning.  Abaye said: Scripture saith, 'the burnt-offering of the Sabbath [shall be burnt] on its Sabbath',  but not the burnt-offering of weekdays on the Sabbath, nor the burnt-offering of weekdays on Festivals.  Raba said, Scripture saith, [no manner of work shall be done on them, save that which every man must eat,] that only may be done of you:  'that', but not its preliminaries;  'only', but not circumcision out of its proper time, which might [otherwise] be inferred a minori.  R. Ashi said: on the first day shall be a solemn rest [Sabbathon]
