פירוש על עבודה זרה 91:5

R. Sheshet argues that the analogy the baraita draws between the mountains and the vegetation seems to imply that just as the mountain was not created to be worshipped, so too the vegetation was not created to be worshipped. Since the baraita states that the vegetation is prohibited, it must follow the opinion of R. Yose son of R. Yehudah who holds that trees that were not planted for idolatry but were then worshipped are prohibited. This view was the topic of some intense discussion in last week’s sugya.
