Avodah Zarah

GEMARA. I quote in contradiction to this: When a city has been captured by besieging troops, all the wives of priests therein are disqualified [to their husbands]!  — R. Mari said: [The soldiers] have no leisure to offer libations, but they have it to satisfy their lust. MISHNAH. IF A HEATHEN SENT TO ISRAELITE CRAFTSMEN A CASK OF YEN NESEK AS THEIR WAGE, THEY ARE ALLOWED TO SAY, GIVE US ITS VALUE IN MONEY';  BUT AFTER [THE WINE] HAS COME INTO THEIR POSSESSION [THE EXCHANGE] IS PROHIBITED. GEMARA. Rab Judah said in the name of Rab: A man is allowed to say to a heathen, 'Go and settle for me the king's portion.'  Against this is quoted: A man may not say to a heathen, 'Go in my place [and give a bribe] to the official'! — Rab retorted: You speak of a case where a man says, 'Go in my place [and give a bribe] to the official.'  But the circumstance [where I give permission is quite different] and is the equivalent of: He may, however, say to him, 'Save me from the official.'  MISHNAH. IF [AN ISRAELITE] SELLS HIS WINE TO A HEATHEN, SHOULD HE HAVE SETTLED THE PRICE BEFORE HE MEASURED IT OUT, THE PURCHASE-MONEY IS PERMITTED; BUT SHOULD HE HAVE MEASURED IT OUT BEFORE HE SETTLED THE PRICE,  THE PURCHASE-MONEY IS PROHIBITED. GEMARA. Amemar said: Acquisition by meshikah  does apply to a Gentile.  You may ascertain this from the practice of the Persians who send presents  to one another and never retract.  R. Ashi said: I certainly maintain that acquisition by meshikah does not apply to a Gentile, and the reason why [the Persians] do not retract is due to the spirit of pride which possesses them.  R. Ashi said: What is my authority for this statement? That which Rab told the [Israelite] wine-sellers, viz., 'When you measure wine for Gentiles, first take the money and then measure for them, and if they have not the cash with them, lend it to them and get it back later so that it should be a loan [of money] with them; for should you not act in this manner, when it becomes yen nesek it will be in your possession and when you receive payment it will be for yen nesek.' Now should it enter your mind [argued Rab Ashi] that acquisition by meshikah does apply to a Gentile,
