Pesachim 3:8 - 4:1

שיש בידו בשר קדש – that becomes invalidated when he lives, for the wall of Jerusalem is the separator of [lighter] holy things.

אם עבר צופים – the name of a place that from there one sees the Temple.

שורפו במקומו – and they don’t trouble him to return [to burn the Hametz or holy meat]

ולאם לאו חוזר ושורפו – As it is written (Leviticus 6:23): “ [but no purification offering may be eaten from which any blood is brought into the Tent of Meeting for expiation] in the sanctuary; any such shall be consumed in fire.” In the place where he eats it, he burns it.

זה וזה – leaven as we have said above and mention that he has leaven in his house, etc., and Holy meat that is with him.

כבחתה – but less than this (i.e., an egg’s bulk), he annuls it in his heart, and Holy meat he burns in his place. And Rabbi Meir holds that his return is like his defilement. Just as defilement through eatables is like that of an egg, for food cannot defile with less than an egg’s worth, so too, he does not return on something that is less than an egg’s worth.

רבי יהודה אומר זה וזה בכזית – He holds that his return is like its prohibition. Just as its prohibition is an olive’s bulk-worth, for an a olive’s worth of leaven or of Holy meat, he is liable, so too, for a olive’s bulk, he returns.

בשר קודש – because of the stringency of Holy meat, he returns even for an olive bulk’s worth. Leaven of non-sacred produce he does not go back other than on an egg’s bulk. And the Halakha is according to the Sages.

מקום שנהגו עד חצות – until half the day.

שלא לעשות – in order that he not be busily engaged by his work and he would forget the [obligation of] ridding of the leavened products and the sacrifice of the Passover offering and the preparation of the Matzah for the Mitzvah [of the Seder].

אל שינה אדם – this is how it should be understood: A person who walks from a place where they don’t do [work] to a place where the do [work], they should place upon him the stringencies of the place where he left from there and not do it (i.e., work), and that is what we hold: A person should not vary from the local custom of the city, it is not because of disputes for here there is no dispute. For what that you said: A person sees him idle would say that this one who is idle is because work is forbidden and that he disputes against all of us; he did not say this, but rather he said: he has no work for how many idle individuals are there in the marketplace all the days of the year. And that which we teach [in this Mishnah] that we lay upon him the strict rules followed in the place from which he has gone forth, is not [in effect] other than when it at the time when it is his intention to return to his place; but if he does not have the intention to return to his place, he practices according to the custom of the people of the place where he went to , whether for leniencies or for stringencies.
