שנים טמאים במת אחד טמא טומאת שבעה -the entire Mishnah is explained further on.

אדם הנוגע במת, טמא טומאת שבעה – as it is written (Numbers 19:11): “He who touches the corpse of any human being shall be impure for seven days.” Because he has become a primary source of Levitical uncleanness/ritual impurity, as the corpse is a progenitor of the primary sources of ritual impurity/אבי אבות הטומאה.

אדם הנוגע בו טמא טומאת ערב – as it is written (Numbers 19:22): “[Whatever that impure person touches shall be impure] and the person who touches him shall be impure until evening.” Because he became a secondary source of impurity/ולד הטומאה, has only has ritual impurity until nightfall/טומאת ערב. But the Sages decreed on a person who has contact with a טמא מת/one made unclean through a corpse while he is still connected to the corpse, that he will be ritually impure seven [days] (see Talmud Avodah Zarah 37b).

כלים הנוגעים במת וכו' – whether metal vessels or vessels or clothing which require only rinsing in order to be restored to Levitical cleanness and clothing, are defiled like the corpse itself, as it is written (Numbers 19:16): “[And in the open, anyone who touches a person] who was killed or died naturally, [or human bone or a grave, shall be impure seven days].” The person who was killed is like a corpse, and this is the law for all the rest of the vessels. Therefore, vessels that come in contact with the corpse become a progenitor of the primary sources of ritual impurity/אבי אבות הטומאה, but vessels [that come in contact] with vessels ae a primary source of ritual impurity for always second-degree of ritual impurity never become like [those vessels] that are first-degree of ritual impurity.

השלישי בין אדם בין כלים – become first-degree of ritual impurity, and are defiled until nightfall.

כיצד ארבעה – vessels that come in contact with a corpse are progenitors of the primary sources of ritual impurity like it (i.e., a corpse). But a person [who is defiled] with utensils [which came in contact with a corpse becomes] a primary source of ritual impurity/אב הטומאה. And vessels [that were defiled by a corpse that came in contact with a person, is also a primary source of ritual impurity, like the person himself, as it is written (Numbers 31:24): “On the seventh day you shall wash your clothes and be pure, [and after that you may enter the camp],” hence you learned that every person who is defiled for seven days of defilement defiles vessels for a defilement of seven days.

הרביעי בין אדם בין כלים -become first-degree of ritual impurity. And the say law applies with “How so- for three?” for one is able to teach that a person who comes in contact with a corpse or vessels with a person are defiled with ritual impurity for seven days; the third, whether a person or vessels are defiled with ritual impurity until nightfall, but from the concluding clause [of the Mishnah] for the fourth who are defiled through contact with a corpse, we understand it, that even a person with utensils that came in contact with a corpse and/or vessels that came in contact with a person is taught that there is a period of defilement for seven days. All the more so, a person with the dead himself, or vessels with a [defiled] person, where there is a defilement of ritual impurity for seven days.

שפוד (a spit) – like a kind of column of metal that is fastened in the tent and upon its end they tie the tent.

אין האוהל מתחשב (the tent does not come into consideration)- because the tent does not defile the spit, therefore it is not considered in the number of the order of the defilements, but rather, all that is placed in the tent of the corpse is like it is touching the corpse itself, and there are only four here. Alternatively, even if the spit is not within the tent, but rather that it touches the tent from outside, nevertheless, the tent does not come into consideration in the number of the order of our Mishnah. And this proved further on/ahead in the Chapter "סכום עבה"/The Thick Coarse Woolen Blanket (Chapter 15), in the Mishnah "טבליות של עץ"/Tables of Wood (Mishnah 2).

שהכלים שלשה – as for example vessels that came in contact with a corpse and vessels [that came in contact] with vessels. And further, vessels are third [degree of ritual uncleanness [which came in contact’ with vessels that are second [degree of ritual uncleanness], all are impure.

והאדם שנים – as for example, a person [who came in contact] with a corpse and a second person [came in contact] with that person that was defiled [through contact] with a corpse. But a third person who has third [who came in contact] with [a person] with second [degree of uncleanness] is ritually pure.

שהוא באמצע – as for example, vessels and a person and vessels. For the fourth, whether it is a person or vessels defiles until nightfall, as we learned from our Mishnah above (see Mishnah 1).

מטמא בגדים – all of this that is not explained [in the Mishnah] as it is written (Leviticus 15:7): “Whoever touches he the body of the one with the discharge shall wash his clothes, [bathe in water, and remain impure until evening],” so we see that he defiles [his] clothing at the time of his contact with the one with the discharge/the person who has gonorrhea.

ואין הבגדים הנוגעים בזב מטמאין בגדים – because the person with the discharge/gonorrhea is a primary source of Levitical uncleanness/אב הטומאה, and the clothes that touch it become first [degree of ritual uncleanness]. But they do not defile other clothing, for a person and vessels do not become susceptible to receiving defilement other than from a primary source of ritual impurity.

והבגדים הנושאין את הזב מטמאין אדם – as for example, lying and sitting of a person with a discharge/gonorrhea which defile a person because they become a primary source of ritual impurity like the person with a discharge/gonorrhea himself As it is written (Leviticus 15:10): “Whoever touches anything that was under him shall be impure until evening.”

ואין אדם הנושא את הזב מטמא את האדם – and even at the time that he carries him prior to his separating. For he is aught other than first degree of ritual impurity and a nothing that is first [degree of ritual impurity] can defile a person.

עד שתצא נפשו – as it is written (Numbers 19:13): “Whoever touches a corpse, the body of a person who has died, [and he does not purify himself, defiles the LORD’s Tabernacle; that person shall be cut off from Israel. Since the water of lustration was not dashed on him, he remains impure; his impurity is still upon him],” that Scripture comes to teach that a person does not defile until he dies.

מגוייד (he who had his arteries opened, bled to death) – cut piecemeal, the language of (Daniel 4:11): “Hew down the tree.”

זוקק ליבום – all the while that he is rapidly passing away/lying on his deathbed, his sister-in-law (i.e., widow of his brother who died without issue) is forbidden to get married

ופוטר מן היבום – if he (i.e., the brother-in-law) died, and he left a son who is rapidly passing away. His wife is exempt from Halitzah/the ceremony that frees the widow of a man who died without children from the obligation to marry one of her deceased husband’s brothers and allows her to remarry [through the removal of a special sandal from the foot of one of her deceased husband’s brothers].

ומאכיל תרומה – if the mother of his mother is an Israelite who was married to a Kohen (see also Mishnah Tractate Yevamot, Chapter 9, Mishnah 5).

ואין מטמאין באוהל – for defilement from a tent is not other either with a complete person, as it is written (Numbers 19:14): “When a person dies in a tent,” or with a limb that is similar to a person, as it states (Numbers 19:16): “or human bone,” just as a human being that has flesh and sews and bones and defiles in a tent, even a limb that has flesh and sinews and bones defiles in a tent.
