What are the examples of compound tumah? TB Nazir 43

We know that one of the three prohibitions a nazir must observe is not coming into contact with a dead body (tumat met-טומאת מת). There are two significant verses in the Torah that discuss this prohibition “Throughout the term that they have set apart for YHVH, they shall not go in where there is a dead person.” (Numbers 6:6) and “Even if their father or mother, or their brother or sister should die, they must not become defiled (לֹא יִטַּמָּא) for any of them, since hair set apart for their God is upon their head” (Numbers 6:7) Rabba understands these two verses to represent two separate prohibitions. The nazir is forbidden to go in where there’s a corpse and he is forbidden to become tamei. If he violates both these prohibitions, he is liable for two different sets of lashes. However, he also holds that a person is not liable for multiple lashes when the nazir comes into contact with consecutive corpses.

The Gemara raises the problem as soon as the nazir enters a house where a dead body is located, he becomes tamei. How can he be liable for two sets of lashes for he is already tamei before touching the corpse?! This is another example of consecutive contact. The Gemara tries to find a solution for Rabba where a person would enter a house where there is a corpse and become tamei at the same time. Let’s call this compound tumah as opposed to consecutive tumah.

After rejecting many suggestions, today’s daf TB Nazir 43 presents two solutions albeit the first is not realistic at all.

“Rav Pappa said: We are dealing with a case where one entered into a house in a chest, a box, or a cabinet, which are not susceptible to ritual impurity and which protect their contents from impurity when they can hold more than forty se’a, and another came and opened the cover of the vessel from over him. In that case contracting impurity and entering the enclosure occur simultaneously.” (Sefaraia.org translation) Tosefot ד"ה כגון adds that the person inside the box has to physically help (מסייע) open the box in order to be liable for the prohibition of “they shall not go in.” If he does not, actively participate in the violation, he is not liable.

“Mar bar Rav Ashi said: It is referring to a case where one entered the house when someone there was dying, and the latter’s soul departed when he was sitting there. In that case too, contracting impurity and entering the enclosure with a corpse occur simultaneously. Since there was no corpse in the enclosure when he entered, he is considered to have entered an enclosure with a corpse at the moment the person died” (Sefaria.org translation) I can see this scenario happening. The nazir is willing to take the chance to say goodbye to the person who was about to die even though he might ultimately violate to prohibitions according to Rabba.
