 In each pamphlet, he explicated 14 Mishnayot (two per day), two laws from the Shulchan Aruch, two laws from the Rambam, and a selection from Tanakh.The first pamphlets contained commentaries that Kehati compiled from local yeshiva students.Frustrated at the inconsistencies in the commentary quality and approach, Kehati hired Rabbi Zvi A. Yehuda, who taught Mishna on an Israel Broadcasting Service (Kol Israel) radio program, to help develop a consistent approach to his commentary.
