Study Guide Shabbat 25 Today's daf is dedicated l'ilui nishmat Moshe ben Betzalel and Sprintze Pessel z"l by his daughter Rachel Levy and by Matt Nelson in honor of Liz Kershner's birthday. Happy birthday! From where in the Torah do we learn that one can benefit from teruma that became impure while one is burning it? Three answers are brought. One is derived from ma'aser - one can't benefit from burning impure ma'aser but it is implied that in another case one would be allowed to. This case is attributed to teruma. However, the gemara questions - why teruma and not sanctified items? Why can't one light using tar? One is concerned since it smells bad, one won't eat by light of the candles - why is this a problem? Shabbat candles are an obligation so that there will be light in the house on Shabbat. Washing one's body before Shabbat is optional. A verse from Eicha is brought regarding a lamentation for the good things that they are missing when they went into exile. The beginning of the verse is explained as a reference to lighting Shabbat candles. For the end of the verse several explanations are brought regarding what is a sign of prosperity that they were missing and then the gemara brings a braita with four tannaitic opinions about "Who is considered wealthy?" An opinion is brought that one cannot light with sap from a balsam tree. Two reasons for this are brought.
