Today's daf is sponsored by Tova and David Kestenbaum in loving memory of Tova's father, Rabbi Dr. Israel Rivkin z"l, on the occasion of his first yahrzeit. "My father was a pillar of strength and love for our family, a passionate learner of Torah, and a man whose chessed for his community and Klal Yisrael knew no bounds. He was deeply grateful to be living in Israel, together with my mother, surrounded by generations of descendants — a dream he cherished and fulfilled with joy and pride. יהי זכרו ברוך"
