Rujukan Mishnah untuk Imamat 15:19: Mishnah Eduyot, Mishnah Niddah, Mishnah Horayot & Mishnah Ketubot

Shammai says: “For all women [who begin to menstruate] it suffices [to reckon their impurity from] the time [of their discovering it].” And Hillel says: “[Their impurity is reckoned backwards] from the [last] examination to the [previous] examination, even if this covers many days.” But the Sages say: “Neither according to the opinion of this one nor according to the opinion of this one, but [they are considered impure for] the past twenty four hours when this lessens the period from the [last] examination to the [previous] examination, and for the period from the [last] examination to the [previous] examination when this lessens the past twenty-four hours.” Any woman who has a regular period, it suffices [to reckon her impurity from] her set time. She who uses testing-cloths [when she has sexual relations], behold this is like an examination: it lessens either the period of the [past] twenty four hours or the period from the [last] examination to the [previous] examination.

Shammai says: for all women it suffices [to reckon] their [period of uncleanness from their time [of discovering the flow]. Hillel ruled: [their period of uncleanness is to be reckoned retroactively] from the [previous] examination to the [last] examination, even if this was many days. The sages say: [the law is] not like the words of these or the words of those, but [the women are deemed to have been unclean] during [the preceding] twenty-four hours when this lessens the period from the [previous] examination to the [last] examination, and during the period from the [previous] examination to the [last] examination when this lessens the period of twenty-four hours. For any woman who has a regular period it suffices [to reckon her period of uncleanness from] the time she discovers the flow. And if a woman uses rags when she has marital intercourse, this is like an examination which lessens either the period of the [past] twenty-four hours or the period from the [previous] examination to the [last] examination.

If the court ruled that an entire principle has to be uprooted; if they said that [the law concerning the] menstruant is not found in the Torah or the [law concerning the] Sabbath is not found in the torah or [the law concerning] idolatry is not found in the torah, they are exempt. If, however, they ruled that a part [of a commandment] was to be annulled and a part fulfilled, they are liable. How is this so? If they said: [the law concerning the] menstruant occurs in the Torah but if a man has relations with a woman that awaits a day corresponding to a day he is exempt, [or that the law concerning the] Sabbath occurs in the Torah but if a man carries anything from a private domain to a public domain he is exempt, [or that the law of] idolatry occurs in the Torah, but if a man only bows down to an idol he is exempt, they are liable, for it says, “And if some matter escapes [the notice of the congregation]” (Leviticus 4:13), “some matter” but not the entire principle.
