In classical rabbinic interpretation The parashah is discussed in these rabbinic sources from the era of the Mishnah and the Talmud: Leviticus chapter 21 Rabbi Tanhum son of Rabbi Hannilai taught that was one of two sections in the Torah (along with , on the Red Cow) that Moses gave us in writing that are both pure, dealing with the law of purity.

Rabbi Simeon ben Lakish (Resh Lakish), however, said that the Torah was transmitted in its entirety, as , "Take this book of the law." The Gemara reported that Rabbi Johanan interpreted , "Take this book of the law," to refer to the time after the Torah had been joined together from its several parts. And the Gemara suggested that Resh Lakish interpreted , "in a roll of the book written of me," to indicate that the whole Torah is called a "roll," as says, "And he said to me, 'What do you see?' And I answered, 'I see a flying roll.'"

They were: the section of the priests in , the section of the Levites in (as the Levites were required for the service of song on that day), the section of the unclean (who would be required to keep the Passover in the second month) in ,
