But in this matter there are some things forbidden, and the cause of the prohibition is lest any man should stir the fire on the Sabbath. For example, food that has not been cooked as much as it requires, or hot water that has not been sufficiently heated, or food which has had the requisite cooking, but which improves all the time that it is left to stew, must not be left on the fire on the Sabbath, even though it may have been placed there, whilst it was yet day on the Friday. This has been decreed, lest one should stir the coals in order to finish the cooking thereof, or to stew it. Therefore, if the fire be swept up, or covered with ashes, or with the coarse part of flax, or if the coals have ceased to glow, for then they are looked upon as covered with ashes, or if the fire had been made with straw or stubble, or with the dung of small cattle, then, as there are no burning coals, it is lawful to leave the food there on the Sabbath, for in this case the man's mind will be turned away from the cooking, and the only object of the decree is, lest the fire should be stirred."
