According to Halachah 1, why is wine permitted even with an open entrance when the Jew lives in the same courtyard as the gentile?
Rambam rules that when a Jew lives in the same courtyard, the gentile is always afraid of a surprise visit — 'He may suddenly enter and find me here' — making accidental access impossible and the wine permitted.
Question 2
What is the ruling if a Jew deposits wine with a gentile under only ONE seal, and the gentile designates a specific corner for it?
Halachah 8: one seal is insufficient for full permission. The wine is forbidden to drink (since we suspect the gentile may have entered), but permitted for financial benefit — provided the gentile designated a specific corner for it.
Question 3
Which of the following is listed in Halachah 12 as a Rabbinic prohibition enacted as a safeguard against libation, even though no actual libation is involved?
Halachah 12 lists rabbinic safeguards including: a gentile may not mix water into Jewish wine lest he come to pour wine into water. This is a prophylactic decree — the actual act is benign, but the slippery slope is not.
Question 4
A worker is hired to transport '100 barrels of beer for 100 p'rutot' but one barrel turns out to be gentile wine (Halachah 17). What is the ruling on his entire wage?
Halachah 17: since the wage was quoted as a collective lump sum ('100 barrels for 100 p'rutot'), the entire wage is forbidden. He would not have been paid at all had he not transported all the barrels — so the wine barrel's transport is inseparable from the total payment.
Question 5
According to Halachah 27, if a gentile intentionally touches Jewish wine and renders it forbidden, what is his financial obligation?
Halachah 27: when a gentile intentionally touches Jewish wine (rendering it forbidden), he is liable for damages. The damage is assessed at the wine's full value before it was touched — the moment of contact is the reference point for the loss.
