And if it were so,

<<let it teach:

<<if he transgressed

<<and baked,

<<it is permitted!

<<Rav Ada bar Masna said:

<<the tanna

<<a remedy

<<that is permitted

<<teaches;

<<a remedy

<<that is prohibited

<<he does not

<<teach.

Come and hear:

<<one

<<who set

<<an eiruv tavshilin

<<he

<<may bake,

<<cook

<<and insulate [food];

<<and if

<<he wishes

<<to eat

<<his eiruv,

<<the choice is

<<in his hand.

<<If he ate it

<<before

<<he baked,

<<before

<<he insulated,

<<he

<<may not

<<bake,

<<nor

<<cook,

<<nor

<<insulate,

<<neither

<<for himself

<<nor

<<for others;

<<nor

<<may others

<<bake

<<or cook

<<for him.

But

<<cooks

<<he

<<for Yom Tov,

<<and if

<<he left over,

<<it is left over

<<for Shabbos,

<<provided

<<that he not

<<use artifice;

<<and if

<<he used artifice,

<<it is prohibited!

Rav Ashi said:

<<artifice

<<you speak of?

<<Different is

<<artifice,

<<for were stringent

<<about it

<<the Rabbis

<<more

<<than intentional [transgression].

Rav Nachman bar Yitzchak

<<said:

<<this —

<<whose is it?

<<Chananya

<<it is,

<<in accordance with

<<Beis Shammai.

<<As it is taught:

<<Chananya

<<says:

<<Beis Shammai

<<say:

<<one may not

<<bake

<<unless

<<he made an eiruv

<<with bread,

<<and one may not

<<cook

<<unless

<<he made an eiruv

<<with a cooked dish,

<<and one may not

<<insulate

<<unless

<<there was

<<hot water

<<insulated

<<from the eve of Yom Tov;

and Beis Hillel

<<say:

<<he makes an eiruv

<<with a cooked dish,

<<one,

<<and does

<<with it

<<all

<<his needs.

(We learned:)

<<one who tithes

<<his produce

<<on Shabbos —

<<unwittingly,

<<he may eat;

<<intentionally,

<<he may not

<<eat.

<<It is necessary only

<<where he has

<<produce

<<other.

Come and hear:

<<one who immerses

<<his vessels

<<on Shabbos —

<<unwittingly,

<<he may use

<<them;

<<intentionally,

<<he may not

<<use

<<them.

It is necessary only

<<where he has

<<vessels

<<other;

<<alternatively,

<<it is possible

<<by borrowing.

Come and hear:

<<one who cooks

<<on Shabbos —

<<unwittingly,

<<he may eat;

<<intentionally,

<<he may not

<<eat.

<<A prohibition

<<of Shabbos

<<is different.

‘Beis Shammai

<<say:

<<two

<<cooked dishes.’

<<Our Mishnah

<<is not

<<like

<<this

<<tanna,

<<as it is taught:

<<Rabbi Shimon ben Elazar said:

<<agree

<<Beis Shammai

<<and Beis Hillel

<<regarding

<<two

<<cooked dishes,

<<that one needs [them];

<<about what

<<did they disagree?

<<About

<<a fish

<<and an egg

<<on it,

<<for Beis Shammai

<<say:

<<two

<<cooked dishes;

<<and Beis Hillel

<<say:

<<a cooked dish,

<<one.

<<And they agree

<<that if

<<he beat

<<an egg

<<and put it

<<into

<<the fish,

<<or

<<he chopped

<<leeks

<<and put them

<<into

<<the fish,

<<that they are

<<two

<<cooked dishes.

Rava said:

<<the halacha is

<<like the tanna

<<of ours,

<<in accordance with

<<Beis Hillel.

‘If he ate it

<<or

<<it was lost,

<<he

<<may not

<<cook

<<relying on it

<<etc.’

<<Abaye said:

<<we have a tradition:

<<if he began

<<his dough

<<and was eaten

<<his eiruv,

<<he may finish.

MISHNAH:

<<If [Yom Tov] occurs

<<to be

<<after

<<Shabbos,

<<Beis Shammai

<<say:

<<one immerses

<<everything

<<before

<<Shabbos;

<<and Beis Hillel

<<say:

<<vessels

<<before

<<Shabbos,

<<and a person

<<on Shabbos.

And they agree

<<that one may connect

<<the water

<<in a vessel of

<<stone

<<to purify it,

<<but

<<not

<<immerse [it].

<<And one may immerse

<<from one purpose

<<to another,

<<and from one group

<<to another.

GEMARA:

<<According to all

<<at least,

<<a vessel

<<on Shabbos,

<<no.

<<What is the reason?

<<Rabba said:

<<a decree
