Parah 11:3 - 11:4

אם יש בה כביצה – for a person who eats less than an egg’s bulk does not defile.

בין הרה בין טמאה המים טמאים – for the purification of impure heave-offering next to the purification offering.

והאוכלה חייב מיתה – that was defiled in the waters of lustration at the time of his consuming it, and the heave-offering in the defilement of the body is [punishable] by death.

ר' יוסי אומר בטהורה המים טהורים – for Rabbi Yossi holds that the person who is pure for heave-offering does not defile the waters of lustration/purification water. But the Halakha is not according to Rabbi Yossi.

שהכניס ראשו ורובו בתוך מי חטאת – the Rabbis decreed on all who come with their head and the majority of their body in drawn water, as is explained in the first chapter of Tractate Shabbat (see Mishnah 4), and it is one of the eighteen matters that they decreed on that day (i.e., the day when Rabban Gamaliel was removed as the President of the Academy – see Tractate Berakhot 28a) and these are the drawn waters of the waters of purification, therefore, when he placed his head and the majority of his body in them, he was defiled, and from when he was defiled, and he is not pure for the waters of purification, the waters of purification return and -defile him and he becomes first degree of ritual defilement, for the waters of purification defile the pure person to them, but he who is not ritual pure to them, they defile him.

כל הטעון ביאת מים מדברי תורה – as for example, a person who comes in contact with all primary sources of ritual uncleanness (see the first chapter of Tractate Kelim)

מטמא את הקודש ואת התרומה – because it is first-degree of ritual uncleanness, it makes it second-degree of ritual uncleanness and with tithes, and third-degree of ritual uncleanness with heave-offerings and fourth degree of ritual uncleanness with Holy Things.

לאחר ביאתו – that he ritually immersed and did not have a sunset pass, he has the law of second degree of ritual uncleanness, and makes heave-offering third-degree of ritual uncleanness and Holy Things fourth-degree of ritual uncleanness.

וחכמים אומרים פוסל בקודש – in the same way that a person who immersed himself that day invalidates heave-offering, so he invalidates Holy Things, but he does not defile Holy Things, for since he immersed his defilement is weakened, and he is made equivalent to something invalid, [but] he is not made equivalent to being impure.

ואם בא אל המקדש – all who are required to ritually immerse from the [Written] Torah, who comes to the Sanctuary, that is to the Israelite Courtyard, even after he had immersed prior to his sunset, is liable [for extirpation]. And even to the Women’s Courtyard, a person who immersed himself that day is forbidden to enter, but he is not liable [for extirpation] other than in the Israelite courtyard.
