The story according to the Talmud goes as follows:
A new type of oven is brought before the Sanhedrin. The rabbis debate whether or not this oven is susceptible to ritual impurity.[1] Rabbi Eliezer ben Hurcanus argues that the oven is ritually pure, while the other rabbis, including the nasi Rabban Gamaliel[citation needed], argue that the oven is impure.[1] When none of Rabbi Eliezer's arguments convince his colleagues, he says that if he's right, the trees will give him a sign.[1] At this point, the tree leaps from the ground and moves far away.[1]
The other rabbis tell Rabbi Eliezer that the movement of the tree was not evidence of what he was arguing.[1] Rabbi Eliezer then says if the halacha is according to him, an irrigation canal will give them a sign.[1] The canal begins to flow backwards, but again the other rabbis are not convinced.[1] Rabbi Eliezer cries out, "If the halakha is in accordance with my opinion, the walls of the study hall will prove it." The walls of the study hall begin to fall,[1] but are then scolded by Rabbi Joshua ben Hananiah[citation needed] who reprimands the walls for interfering in a debate among scholars[citation needed]. Out of respect for Rabbi Joshua, they do not continue to fall, but out of respect for Rabbi Eliezer, they do not return to their original places.[citation needed]
In frustration, Rabbi Eliezer finally argues that if the halakha is according to his opinion, God himself will say so.[citation needed] God then speaks directly to the arguing rabbis, saying that Rabbi Eliezer's opinion is correct.[2] Rabbi Joshua responds, "It [the Torah] is not in heaven".[2] Upon hearing Rabbi Joshua's response, God laughed and stated, "My children have defeated me!"[2]
