140 Avodah Zarah 3/4-6

(4) Proklos son of Plosfos asked Rabban Gamliel [a question] in Akko, while he was bathing in the bathhouse of Aphrodite. He said to him: "It is written in your Torah (Deuteronomy 13:18): 'And let none of the condemned cling to your hand;' why then are you bathing in the bathhouse of Aphrodite? He said to him: one does not respond [to halakhic questions] in the bathhouse. When he left, he said to him: "I did not come into her territory; she came into my territory. They did not say [when they built this bathhouse]: 'Let us make a beautiful bathhouse for Aphrodite.' Rather, they said: 'Let us make Aphrodite for the beauty of the bathhouse.' Another reason: [even] if they gave you a lot of money, you would not enter before your idolatry naked and defiled and urinating in front of it. Yet she stands on the sewer pipe and the entire nation urinates in front of her. The verse (Deuteronomy 12:3) only applies to "their gods;" that which he treats like a god is prohibited, and that which he does not treat like a god is permitted."

(5) Non-Jews who worship the mountains and hills, they [the mountains and hills themselves] are permitted, but that which is upon them is forbidden, as it says (Deuteronomy 7:25): You shall not covet the gold and silver that is upon them and take it. Rabbi Yose the Galilean said (Deuteronomy 12:2): "Their gods upon the mountains," but the mountains are not their gods; their gods "upon the hills," but the hills are not their gods. And why are Asherah trees forbidden? Because humans hands were involved in [planting] them, and any [idolatrous] thing that human hands were involved in is forbidden. Rabbi Akiva said: I will expound [the verse] and rule before you, everywhere that you find a tall mountain, a raised hill, or a verdant tree know that there is idol worship there.

(6) One whose house abuts [a house of] idolatry, and [his own house] collapses, it is prohibited to rebuild it. How should he proceed? He should gather it four cubits into his own [space] and build. If it [the wall that collapsed] belonged both to him and to the [house of] idolatry, the [respective] law applies to each half [and only his own half may be rebuilt]. The stones, wood, and dust [of a house of idolatry] have a ritual impurity like that of vermin [i.e. through contact], as it says (Deuteronomy 7:26): You shall utterly detest it. Rabbi Akiva says: like that of a menstruating woman, as it says (Isaiah 30:22): "You will banish them like a menstruating woman. ‘Get out!’ you will say to it.” Just as a menstruating woman renders objects impure through carrying, so too does idol worship render objects impure through carrying.
