GEVURAH: YESHIVAT HAVERIM יְשִׁיבָה חברים – BABYLONIAN TALMUD p89

MISHNA IV.: (A vessel) not covered during daylight must not be covered after dark. If, after
having been covered, it became uncovered, it is permitted to cover it again. A pitcher may be
filled with cold victuals and put under a pillow (to keep it cool).
GEMARA: R. Jehudah in the name of Samuel said: “It is permitted to store cold victuals (to
protect them from the sun).” Said R. Joseph: “What news came he to teach? Have we not
learned this in the above Mishna?” Abayi answered: “A great deal! From the Mishna I would
infer that only such things as are not usually stored are permissible (for in that case no
precaution lest one put warm victuals under a pillow or bolster for the purpose of generating
heat is necessary); he informs us, however, that even such things as are usually stored are
permissible also.” R. Huna in the name of Rabbi, however, says: “It is prohibited.” Were we not
taught that Rabbi has permitted this? This presents no difficulty. In the former instance he did so
when he was not as yet aware of the following decision of R. Ishmael b. Jossi. Rabbi at one time
decided that it is forbidden to store cold victuals. Said R. Ishmael b. Jossi to him: “My father
permitted it,” whereupon Rabbi said: “If this sage has once permitted it, so shall it be done.”
Said R. Papa: Come ye and note the mutual respect: Had R. Jossi been alive, he would have had
to show respect to Rabbi; as R. Ishmael, who succeeded his father in every respect, also has
acknowledged Rabbi’s superiority. Still Rabbi accepted his decision.

R. Na’hman said to his slave Doru: “Store some cold victuals for me and bring me warm water
from a Gentile cook-shop.” R. Ami heard this and was angry. Said R. Joseph: “What was the
reason of his anger? Did not R. Na’hman act in accordance with the teachings of the great
masters, Rabh and Samuel?” R. Jehudah in the name of Samuel said: It is permitted to store cold
victuals, and R. Samuel b. R. Itz’hak said in the name of Rabh: Anything that may be consumed
raw is not included in the prohibition relating to cooking by a Gentile; he (R. Ami), however,
was of the opinion that, although it is allowed, a man of note should not practise it (because the layman seeing such things of the scholar he might allow himself still more).
