R. Mordecai said to Rabha that R. Qatina has objected to the above rabbis, who said that if it were not replaced before Sabbath it must not be used, from a Mishna (Kilaim, I. 9), which states plainly that it may be taken out on Sabbath. This question remains.
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.

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
