This week's learning is sponsored by Rebecca Koenigsberg "in honor of my Daf Yomi Buddies in New Haven Connecticut whose companionship has helped me through the more difficult moments in Daf Yomi." This week's learning is sponsored by Rachel Recht in loving memory of her father, Shalom Elimelech ben Efraim Fishel Yehoshua and Esther Weinreb. Today's daf is sponsored "in honor of our father and grandfather, Mark Goldstein. Happy father's day! - From your children and grandchildren." Rava rules on a number of different types of shoes and whether they can be sued for chalitza. There is a debate regarding whether or not the chalitza is good if it is done on the left foot or at nighttime. What is the root of the debate regarding the night? Raba bar Chiya performed a chalitza at night with a slipper not made of leather and on his own, rather than in front of two or three people. Shmuel was upset when he heard this. What issue was he upset about? Two different possibilities are suggested. What is the root of the debate regarding the left foot? There are three main elements to the chalitza ceremony - taking off the shoe, spitting and reciting a text (found in the Torah). Which elements are absolutely necessary and which are not? There is a debate regarding the spitting. What is the law for a deaf-mute performing chalitza, or a minor? There is a tannaitic debate regarding chalitza performed in front of less than three people. Rava says that if the recitation is not critical, one can infer that a mute can perform chalitza. How does this fit with our Mishna that disqualifies the chalitza of a deaf-mute? Due to the difficulty, Rava's statement is changed to read the opposite (or perhaps the opposite statement was made by someone else). It was taught that if the yevama spit before one of the brothers, it disqualifies her from performing yibum with one of the brothers? According to whose opinion is this law stated?
