פירוש על עבודה זרה 120:6

R. Ashi quotes another mishnah that proves that the wine is prohibited only if the non-Jew could take it to collect his loan. The wine in the second clause is essentially being held by the non-Jew as collateral for a loan. If the non-Jew will not let the Jew take the wine, then he has a lien on “this wine.” But if he lets him take the wine, then we can assume his lien is on other wine (or some other collateral). In this case the wine would be permitted. We will learn this mishnah in greater depth later in the chapter.
