Musar sobre Malaquías 1:11

We find this in Tractate Bava Metziya,¹⁸Talmud Bavli, Bava Metziya 114a-b that when Rabbah bar Avuha met Eliyahu… Eliyahu asked him why he had not learned the order of purities. He answered, “If I am not proficient in the four orders [of Mishnah that are commonly learned,] how can I be proficient in all six? Rashi explains there that the four orders refer to the orders of Mo’ed, Nashim, and Nezikin, which are the orders that are applicable today, just as during the time of the Holy Temple. He explains that the fourth order is the order of Kodshim,¹⁹Which deals with the Temple service. as it states,²⁰Malachi 1:11 “In every place that incense is offered to My Name,” regarding which our sages stated in Tractate Menachot,²¹Talmud Bavli, Menachot 110a “This refers to the Torah scholars who engage in studying the laws of the sacrificial offerings, that the verse ascribes it as though they have offered the sacrificial offerings in the Holy Temple.” Rashi continues and explains that when he stated, “How can I be proficient in all six,” he was referring to the Mishnaic orders of Zera’im and Taharot, which do not apply outside of the land of Israel.
