레위기 15:22의 인용 해설

Rabbi Akiva said: From where do we know that an idol defiles by being carried like a menstruant? Because it is said, “You shall cast them [the idols] away as a menstruous woman. Out! You will say to them” (Isaiah 30:22): just as a menstruant defiles by being carried, so does an idol defile by being carried. Rabbi Akiva holds that a person who carries an idol is defiled by the idol, even if he doesn’t touch it and only carries it. He derives this halakhah from a comparison that Isaiah makes between idols and a menstruant. In his exhortation against idolatry Isaiah states that the people of Israel will cast out their idols like a menstruous woman. Leviticus 15:22 teaches that a menstruous woman defiles things not just by touching them but even by sitting on them. From here the rabbis derive that she transmits impurity also by being carried. Rabbi Akiva learns from Isaiah that idols transmit impurity in the same way.

if on the seat This refers to the abovementioned “utensil she sat upon” [:22]. The case is that of a utensil atop her seat, or a utensil atop another utensil. Thus, its ritual impurity is less severe. Scripture does not mention a saddle [see :9], because it speaks of things that are likely to occur; but the law in such a case would be the same.
