Today's daf is sponsored by Gail Licht in loving memory of her father, Harav Avraham Shaul Halevi Licht. "He would have been very proud of his children and grandchildren, all engaged in lives filled with Torah study and acts of chesed. Yasher Koach to my grandson Yaakov Stechler on his siyum of Mishnayot Seder Nezikin and to his dad, Rabbi Aryeh Stechler his siyum of Kiddushin in my dad's memory." May our learning be in memory of all the soldiers and civilians that have been killed and for a zechut for a refuah shleima for all the injured. We continue to pray for the safety of our soldiers, those living in the South under direct attack, those taken captive and all the citizens of Israel. From where do we derive that it is forbidden to derive benefit from the  egla arufa? From what moment does it become forbidden? One cannot derive benefit from the birds brought by a leper. There is a debate between Rabbi Yochanan and Reish Lakish whether it is forbidden from the moment of purchasing the birds or from the moment of slaughter. The latter is derived from the egla arufa. Rabbi Yochanan raises three difficulties against Reish Lakish's position from tannitic sources. After the last question which is not resolved, Reish Lakish answers that it is a subject of debate among tannaim? Three different reasons are brought to explain why the slaughtered bird is the one that is forbidden to benefit from but the live one (that is sent away) is permitted. From where do we derive that it is forbidden to derive benefit from the hair of the nazir? Is the first-born donkey forbidden according to all opinions? From where do we derive the prohibition to derive benefit from milk and meat together? Whether or not it is forbidden is a subject of debate among tannaim. Two different explanations are brought for the source for chulin slaughtered in the Temple.
