תּלמוד אויף שמות 24:12

Rebbi Ḥaggai and Rebbi Jeremiah went to the Bazaar¹¹The translation is tentative; בית חנוותא means “the house of stores”, which might be a description of a shuq even though it is difficult to explain why the word שׁוּקָא was not used. It is not clear what kind of miẓwah the two rabbis performed in the market. In the opinion of R. Eleazar Askari they were agoranomoi, overseers of weights and measures, and Rebbi Ḥaggai recited a benediction before starting to go from stall to stall and checking the balances for correctness since that is a Biblical commandment repeated several times in the Pentateuch (Deut. 25:15, Lev. 19:36) in addition to the prohibition of fraudulent business practices.
The Rome manuscript has instead of בית חנוותא the expression לְמֵי חַטָּאתָה “the water for the ashes of the read heifer”, the drawing of which certainly would need a benediction. The Talmud reports that Rebbi Ḥaggai finished his Talmud studies with Rav Ḥuna I at age 18 and lived to be 160 years old; so, as shown in the commentary to Mishnah 1:1, he still could have seen ashes of the read heifer, but these could not have been preserved at the time of Rebbi Jeremiah who lived during the third and fourth generations of Amoraïm, even if these ashes were uniquely reserved for Cohanim eating Terumah.
R. Zachariah Frankel wants to emend to בֵּית חַתְנוּתָא “place of a wedding” but his reading has no basis in antique or medieval sources.. Rebbi Ḥaggai was quick to recite a blessing. Rebbi Jeremiah said to him: You acted correctly because all commandments need a benediction. And from where that all commandments¹²After establishing benedictions before the consumption of food one establishes now the need for benedictions before the execution of positive commandments (by tradition, only those to be performed at specific times or occasions, not those that are always valid). need a benediction? Rebbi Tanḥuma, Rebbi Abba bar Cahana in the name of Rebbi Eleazar: (Ex. 24:12) “I want to give you the stone tablets, the Torah and the commandment¹³The verse really reads: “both Torah and Commandments”. The double vaw in the verse is essential for R. Eleazar’s argument..” It brackets Torah and commandment. Just as Torah needs a benediction, a commandment also needs benediction.

R. Levi b. Hamma also said in the name of R. Simeon b. Lakish : What means that which is written, "And I will give thee the tables of stone, and the law and the commandment, which I have written, that thou mayest teach them" (Exod. xxiv. 12)? "Tables of stone," i.e. the Decalogue: "law," i.e. the Pentateuch; "commandment," i.e. the Mishnah ; "which I have written," i.e. the Prophets and Hagiographa; "that thou mayest teach them," i.e. the Gemara. The verse teaches that all of them were given to Moses on Sinai.

I have here only the benediction for meals ; whence is the benediction over Torah derived? R. Ishmael said : By a fortiori reasoning — for temporal life one says a benediction ; how much more so for the life of the world to come! R. Hiyya b. Nahmani, the disciple of R. Ishmael, says in the name of R. Ishmael : [This reasoning] is unnecessary ; for it states, "For the good land which He hath given thee" (Deut. viii. 10) and elsewhere it is stated, "And I will give thee the tables of stone, and the law and the commandments," etc. (Exod. xxiv, 12).
