זבים ה׳:ט׳ - ה׳:י׳

והוא בבית הבליעה (and it is in the esophagus/gullet) – all the time that it (i.e., the food) is in the esophagus it defiles clothing, and since it defiles clothing, it defiles two things (i.e., it’s law is like that of a primary source of ritual defilement – that it makes something first degree of ritual impurity and a first makes non-holy produce second-degree of ritual impurity) and invalidates/makes unfit one (i.e., something second degree of ritual impurity makes priest’s due/heave offering unfit).

הכניס ראשו באויר התנור – even though the carrion of the bird exists with the esophagus/gullet of the person who eats it, everything is in the airspace of the over, nevertheless, it (i.e., the oven) is ritually pure. For the oven is not defiled on account of the person, for everything that defiles clothing does not defile humans and earthenware vessels. But because of the carrion of a clean bird it does not become defiled, for it lacks defilement other than the person in his esophagus/gullet.

הקיאה או שבלעה (he vomited it out or swallowed it) – that is he separated from it. That from when it (i.e., the food particles of the carrion of the clean bird) descended to the stomach, it has no defilement, and when it is in his mouth, it has no defilement, for it is written (Leviticus 17:15): “[Any person, whether citizen or stranger,] who eats what has died/"[וכל נפש] אשר תאכל [נבלה]" for it is written, “who has not eaten” – food in the esophagus/gullet.

ובנבילה ובמרכב – all of these are through carrying alone that they defile clothing, but not through touching/coming into contact. Therefore, a person who touches them even though he did not separate is not other than first-degree of Levitical impurity, and he defiles one (making non-holy produce second-degree of ritual impurity) and invalidates/makes unfit one (i.e., heave offering becomes unfit as it becomes third-degree of ritual impurity).

כל הנוגע- as for example food and vessels, for even with those that a person touches defiles two and invalidates/makes unfit one vessels that touch them defile one and invalidate one, and even at the time of their contact/touching.

חוץ מן האדם – that there is from them that if he touched them or carried, that he (as he is first-degree of ritual defilement) defiles two (making non-holy produce second-degree of ritual defilement) and invalidates one (making priest’s due/heave offering third degree of ritual impurity), like those that we stated above.

פירש – even a person, in all of them he defiles one (as he is first-degree of ritual impurity, making non-holy produce second degree of ritual impurity) and invalidates one (priest’s due/heave offering becoming unfit for use), for since he separated from it, he is not other than first-degree of ritual impurity.
