Impurity is inside a house. A surrounding projection (less than a handbreadth at entrance) runs along the top of the walls. Are items directly under the projection impure?
Halacha 2: If the projection encircles the house but is less than a handbreadth at the entrance and impurity is inside the house, items directly under the projection are impure. However, impurity under the projection does not convey impurity into the house (it does not 'enter').
Question 2
Impurity is within the slanted wall of a tent (not inside the tent, not outside). Someone touches the slanted wall from outside. How long are they impure?
Halacha 7: When impurity is within the slanted wall itself, touching from inside = 7 days (directly in contact with the tent); touching from outside = until evening (the outer face is like a vessel that touched the tent).
Question 3
Stone tablets are stacked on the ground, raised 1000 cubits high. Impurity is beneath them. Do items at the sides of the stone column become impure?
Halacha 4: Stone tablets are considered like the ground itself — no matter how elevated, impurity under them pierces straight up and down but does not spread sideways. They do not form an ohel.
Question 4
The edge of a tent is lying flat on the ground and impurity is under that flat edge. Does impurity spread to the interior of the tent?
Halacha 8: The tent edge (kena'f) lying flat on the ground: impurity beneath it or on top of it only pierces straight up and down — it does not spread to the tent interior.
Question 5
A person holds one hand over a corpse and extends the other hand over some vessels, but their hand is less than a handbreadth wide. Are the vessels impure?
Halacha 1 (ch. 18): If the person's hand is less than a handbreadth wide, it cannot serve as a connecting ohel — the vessels remain pure. If the hand is a handbreadth wide, the person joins the impurity and the vessels become impure.
