According to Halacha 2, what is the source for the impurity of carrying a corpse?
Halacha 2 explains that carrying impurity (tum'at masa) for a corpse is from the Oral Tradition, supported by a kal vachomer: if a carcass (lesser impurity) imparts carrying impurity, how much more so a corpse.
Question 2
If a source of impurity is pushed inside someone's throat on a needle without touching the tongue, does the person become impure?
Halacha 3 states: if the impurity does not touch the person's flesh (tongue), the person does not become impure — inner contact (tum'at penimah) is not considered touch.
Question 3
Which vessels can become impure through ohel according to Halacha 10?
Halacha 10 states that ohel applies to both humans and vessels, even a needle — as long as they share a shelter with the corpse.
Question 4
Can a gentile corpse convey ohel impurity?
Halacha 13 states that the corpse of a gentile does not convey ohel impurity — this is from the Oral Tradition, derived from the war with Midian verse which mentions only touching, not ohel.
Question 5
When does a dying person begin to convey corpse impurity?
Halacha 15 (last halacha): A corpse does not impart impurity until the soul actually departs — even one in death throes or with severed vital signs does not impart impurity until death. However, decapitation and bisection count as death even while limbs twitch.
