פירוש על קידושין 97:13

The word “shoneh” (or mishnah) which I have translated as “recite” always refers to reciting Oral Torah and not reading Written Torah. Therefore, when R. Yohanan says “Torah” he must mean midrash, which is exegesis of Torah. Thus we have here the two main forms of Oral Torah—Midrash, which are laws connected to verses, and halakhot, laws taught independent of verses. The latter form is found today in midrashic collections that follow the order of four of the five books of the Torah (there is none on Genesis). The former is found in the Mishnah and Tosefta.
