We may save [enough] food for three meals; what is fit for people [may be saved] for people, what is fit for animals [may be saved] for animals. How so? If a fire broke out on the Sabbath eve, we may save [only enough] food for three meals; if during the morning, we may save [only enough] food for two meals; if in the afternoon, [we may save only enough] food for one meal. R’ Yose says: We may always save [enough] food for three meals.
