Wine belonging to gentile who worship idols (such as the Romans during their imperial era) is forbidden for a Jew to drink. Therefore the sages forbade wine which has belonged to Roman soldiers and even forbade the pottery jugs in which they stored their wine, so none would add water to release the wine which had penetrated the pottery. Not only is drinking the wine forbidden, but even benefit from or use of gentiles’ wine is forbidden. The scholars asked: is one permitted to use pottery jugs to support a bed (using them as legs)? What are the issues under debate? On one hand such use should be forbidden because one is interested in the wine which had saturated the walls of the jug (which strengthens and preserves the jug), so he is using and gaining benefit from the wine which had penetrated the pottery. On the other hand, the use of and benefit from the wine is not direct, it is indirect; he is interested in the wine only because it strengthens the jug so it can support the bed. (The Talmudic sages were divided on this issue.)
