R’ Eliezer says: If Yom Tov adjoins the Sabbath either before it or after it — a person may make two eruvin and declare, ‘‘My eruv [for] the first is to the east and [for] the second to the west’‘; ‘‘[for] the first to the west and [for] the second to the east’’; ‘‘My eruv is [for] the first, but [for] the second I am as my townspeople’’; [or] ‘‘My eruv is [for] the second, but [for] the first I am as my townspeople.’’ But the Sages say: He makes an eruv to one direction or he makes no eruv at all; either he makes an eruv for both days or he makes no eruv at all. How should one proceed? He should take it on the first and stay with it until nightfall, then take it and go. On the second, he should stay with it until nightfall, then eat it. Thus he benefits in his walking [area], and he benefits from his eruv. If it was eaten on the first the eruv is valid for the first, but the eruv is not valid for the second. Said R’ Eliezer: [So] you agree with me that they are two [periods of] holiness!

R’ Yehudah says: [If before] Rosh Hashanah there was concern lest [Elul] be full, a person may make two eruvin and declare, ‘‘My eruv for the first is to the east, and for the second to the west’’; ‘‘For the first to the west, and for the second to the east’’; ‘‘My eruv is for the first, but for the second [I am] as my townspeople’’; [or] ‘‘My eruv is for the second, but for the first [I am] as my townspeople.’’ But the Sages did not agree with him.

Additionally, R’ Yehudah said: A person may stipulate a condition concerning a basket on the first day of Yom Tov and eat it on the second. And so also, an egg laid on the first may be eaten on the second. But the Sages did not agree with him.

R’ Dosa ben Harkinas says: He who leads the prayers on the Yom Tov of Rosh Hashanah says, ‘Fortify us, O HASHEM, our God, on this Rosh Chodesh, whether [it is] today or whether [it will be] tomorrow’’; and on the morrow he says,’’ . . . whether [it is] today or whether [it was] yesterday.’’ But the Sages did not agree with him.
