Rabbi Yitzḥak interpreted the verse regarding the portions of the Torah. “There are sixty queens,” these are the sixty tractates of halakhot. “And eighty concubines,” these are the eighty portions in Torat Kohanim.25This is the midrash halakha on the book of Leviticus. “And young women without number,” these are the Tosefta.26The Tosefta contains tannaitic material [baraitot] that was not included in the Mishna. “One is [my faultless dove],” they dispute each other, but all of them expound it from one source, from one halakha, from a verbal analogy, from an a fortiori inference.
