['This mishna cites a list of fuels and wicks that one may not use in kindling the Shabbat lights, either because their use might induce one to perform a prohibited labor on Shabbat or because they are not in keeping with the deference due Shabbat. The mishna begins by listing the materials that one may not use as wicks. That is followed by a list of the substances that one may not use as fuel.
With what may one light the Shabbat lamp, and with what may one not light it? With regard to types of prohibited wicks, one may light neither with cedar bast [lekhesh], nor with uncombed flax [ḥosen], nor with raw silk [kalakh], nor with willow bast [petilat ha’idan], nor with desert weed [petilat hamidbar], nor with green moss that is on the surface of the water. With regard to types of prohibited oils, one may light neither with pitch [zefet], nor with wax [sha’ava], nor with castor oil [shemen kik], nor with burnt oil [shemen sereifa], nor with fat from a sheep’s tail [alya], nor with tallow [ḥelev]. Naḥum the Mede says: One may light with boiled tallow. And the Rabbis say: Both tallow that was boiled and tallow that was not boiled, one may not light with them.', 'In continuation of the previous mishna, this mishna adds that one may not light with burnt oil on a Festival, as the Gemara will explain below. With regard to lighting Shabbat lamps, there were Sages who prohibited the use of specific oils. Rabbi Yishmael says that one may not light with tar [itran] in deference to Shabbat because tar smells bad and disturbs those in the house. And the Rabbis permit lighting with all oils for lamps as long as they burn properly; with sesame oil, with nut oil, with turnip oil, with fish oil, with gourd oil, with tar, and even with naphtha [neft]. Rabbi Tarfon says: One may light only with olive oil in deference to Shabbat, as it is the choicest and most pleasant of the oils.', 'Of all substances that emerge from the tree, one may light only with flax on Shabbat (Tosafot) because the other substances do not burn well. And of all substances that emerge from the tree, the only substance that becomes ritually impure with impurity transmitted by tents over a corpse is flax. If there is a dead body inside a house or a tent that is made from any materials that originate from a tree, everything in the house becomes ritually impure. However, only in the case of flax does the tent itself become impure. The wick of a garment, i.e., cloth made into a wick for a lamp, that one folded it into a size and shape suitable for a wick, but did not yet singe it slightly in order to facilitate its lighting, Rabbi Eliezer says: This wick is ritually impure. With regard to the laws of ritual impurity, it can, like other garments, still become ritually impure and one may not light with it on Shabbat. Rabbi Akiva says: It is ritually pure and one may even light with it on Shabbat.', 'The fundamental dispute in this mishna is with regard to the determination whether or not indirect acts of kindling and extinguishing fall within the parameters of the prohibition on Shabbat. The Rabbis said: A person may not pierce a hole in an eggshell and fill it with oil, and place it over the mouth of a lamp so that the egg will drip additional oil into the lamp and thereby extend the time that it burns. And this is the ruling even if it is not an actual egg but an earthenware vessel. And Rabbi Yehuda permits doing so. However, if the craftsman, who crafts ceramic vessels, attached the egg to the lamp from the outset, one is permitted to fill it with oil because it constitutes a single, large vessel. The Rabbis decreed that a person may not fill a bowl with oil, and place it beside the lamp, and place the unlit head of the wick into the bowl so that it draws additional oil from the bowl and thereby extend the time that the lamp burns. And Rabbi Yehuda permits doing so.', 'One who extinguishes the lamp on Shabbat because he is afraid due to gentiles, from whom he is hiding in his home, and due to thieves, or if one is afraid due to an evil spirit, i.e., he is depressed and prefers sitting in the dark, or if he extinguished the flame due to the sick person so that he will sleep, he is exempt. However, in a case where he extinguishes the flame in order to spare the lamp, spare the oil, or spare the wick, he is liable. Rabbi Yosei exempts him in all of those cases, as in his opinion no labor prohibited by Torah law is being performed by extinguishing the flame, except for the case where he seeks to spare the wick. Only in that case is extinguishing a creative action because he makes the wick into charcoal by extinguishing the flame.', 'This mishna concludes the aggadic treatment of the topic of kindling the Shabbat lights. For three transgressions women are punished and die during childbirth: For the fact that they are not careful in observing the laws of a menstruating woman, and in separating ḥalla from the dough, and in lighting the Shabbat lamp.', 'There are three things a person must say in his home on Shabbat eve at nightfall and not before. The mishna elaborates: He should ask the members of his household, have you tithed the crop that required tithing? Have you placed the eiruv for joining the courtyards and joining the Shabbat borders? If you have done so, light the lamp in honor of Shabbat. The Sages stated a principle: If the time arrives on Friday when there is uncertainty whether it is nightfall and uncertainty whether it is not yet nightfall, one may not tithe the crop that has definitely not been tithed, and one may not immerse ritually impure vessels in a ritual bath to render them ritually pure, and one may not light the Shabbat lights. However, one may tithe demai, doubtfully tithed produce, which must be tithed due to mere suspicion. And one may place an eiruv and insulate the hot water to be used on Shabbat.']
