Today's daf is sponsored by Terri Krivosha and Rabbi Hayim Herring to mark the end of shloshim for Terri's mother, Cheni Mindyl bat Yerachmiel HaKohen v'Shima Feiga. Today's daf is sponsored by Caroline Ofstein and Medinah Korn in loving memory of Helen Abelesz, z"l, on her shloshim. "She was a dearly cherished friend who gifted us with her strength, wisdom, inspiration and incredible emuna, and she is sorely missed by the many who loved her. Yehi zichrah baruch." The commandment to honor your elders - does this mean someone who is old, someone who is learned and old or just someone who is learned (even if they are not old)? Does one need to spend money to observe this commandment? Does one need to interrupt one's work to stand for an elder? Does this apply to non-Jews? The elder has a responsibility not to walk in a place where too many people will need to stand up for him. Does a father need to stand for a child who is his teacher? Does that child need to stand in respect for his father? er?
