{Beitza 4b continues}
And an egg which was laid on Shabbat or Yom Tov, it is no question that eating it is forbidden, but even moving it is forbidden,
{Beitza 3b}
For they learnt {in a brayta}: both an egg which was laid on Yom Tov and an egg which was laid on Shabbat, we do not move it, not to cover a vessel nor to support the legs of a bed therewith, but we may upturn a vessel upon it such that it does not break, and its doubt {that it was laid on this day} is forbidden, and if it was mixed with 1000, they are all forbidden.

And this that we said {above}, "Shabbat and Yom Tov {one after another}, what is laid on this one is forbidden in that one," it does not matter whether it is Shabbat after Yom Tov or Yom Tov after Shabbat, for we establish like Rabba that weekday prepares for Shabbat and weekday prepares for Yom Tov, but Yom Tov does not prepare for Shabbat and Shabbat does not prepare for Yom Tov.
{Beitza 4a}
And a brayta also says so: It it was laid on Shabbat it may be eaten on Yom Tov. If it was laid on Yom Tov it may be eaten on Shabbat. Rabbi Yehuda says in the name of Rabbi Eliezer: This is still an instance of dispute. For Bet Shammai say it may be eaten and Bet Hillel say it may not be eaten.
And we establish like Rabbi Yehuda.

And we also say: The host of Rav Ada bar Ahava had these eggs from Yom Tov to Shabbat {and it was Yom Tov}. He came before him. He said to him {Rav Ada}: May one roast them today in order to eat them tomorrow?
He {Rav Ada} said: What are your thoughts? That {in case of dispute between} Rav and Rabbi Yochanan, the halacha is like Rabbi Yochanan? Until this point Rabbi Yochanan only permitted to swallow {in this case, raw} on the next day. But to handle it in its day, no.
For they learnt {in a brayta}: Both an egg which was laid on Shabbat and an egg which was laid on Yom Tov, we do not move it, not to cover a vessel with it nor to support the legs of a bed.

The host of Rav Pappa had these eggs from Shabbat going into Yom Tov. He came before Rav Pappa {on Shabbat}. He said to him {Rav Pappa}: May one eat them tomorrow?
He {Rav Pappa} said to him: Go now, and come {back} tomorrow {and ask again}, for Rav would not appoint an Amorah {expounder} by himself from Yom Tov{'s commencement} until the next day, because of intoxication.
When he came the next day, he said to him: Had I not waited until today I would have erred and told you that {in case of dispute between} Rav and Rabbi Yochanan, the halacha is like Rabbi Yochanan. {However}, So said Rava: The halacha is like Rav in these three, whether lenient or stringent.

And branches which fell off of a palm tree on Shabbat, it is forbidden to burn them on Yom Tov by themselves because of the hachana of Rabba. And if they fell from a palm tree on Yom Tov, it is forbidden to burn them on Yom Tov by themselves because of nolad, and the Sages forbad them lest he ascend and separate {them from the tree himself}. But if they fell directly from the tree into the oven, we may do with them as Rav Matna.
For Rav Matna said: Branches which fell from the palm tree into the oven on Yom Tov, he may increase upon them prepared wood and use it as firewood. And even though he turns over the forbidden {wood}, since
