Avodah Zarah 3:8-9

Avodah Zara 3:8

One may not sit in the shade of an asheira but if one did so, he remains ritually clean. Similarly, one may not pass under an asheira but if one did so, he remains ritually clean. If an asheira extends into the public domain and a person passes under it, he remains ritually clean. One may plant vegetables under an asheira in the rainy season (when the shade is actually counterproductive) but not in the summer (when the asheira’s shade would be beneficial). Lettuce may not be planted under an asheira, neither in the summer nor in the rainy season (because the shade is always beneficial to lettuce). Rabbi Yosi says that not even vegetables may be planted there in the rainy season because dead leaves fall on them and serve as compost.

Avodah Zara 3:9

If a person took wood from an asheira, he is not permitted to benefit from it. Let’s say that he used it to heat a (clay) oven. If the oven is new (so that firing it completes its manufacture) it must be dismantled; if the oven is old, it must be permitted to cool. If he baked a loaf in the oven, one is not permitted to benefit from it; if it became mixed up with other loaves, one is not permitted to benefit from any of them. Rabbi Eliezer says that the monetary value of the prohibited loaf must be thrown into the Dead Sea (which would then permit the other loaves); the Sages said to him that objects of idolatry cannot be redeemed. If one took a wooden needle from an asheira, he is not permitted to benefit from it. If he used it to weave a garment, one may not benefit from the garment. If the garment got mixed up with other garments, and then they with still other garments, benefit is prohibited from all of them. Rabbi Eliezer says that the monetary value of the prohibited garment must be thrown into the Dead Sea (which would then permit the other garments); the Sages said to him that objects of idolatry cannot be redeemed.
