Parashat Behar-Bechukotai (Leviticus 25:1-27:34)
During the rabbinic debate over the Oven of Akhnai, Rabbi Eliezer and the rabbis disagree about the purity of an oven (Baba Metzia 58b-59a). Rabbi Eliezer is convinced he is right and, during the argument, miracles prove he is correct: a carob tree moves, a stream flows backward, the walls of the beit midrash tremble, and even a Bat Kol — a voice from heaven — cries out against the rabbis: “Why do you dispute with Rabbi Eliezer? In all matters, the halachah agrees with him.”
