Parashas Eikev · Passuk 7:25
You shall consign the images of their gods to the fire; you shall not covet the silver and gold on them and keep it for yourselves, lest you be ensnared thereby; for that is abhorrent to the ETERNAL your God.
Torah Temimah points to Avodah Zarah 45a.
TT lemma: כסף וזהב עליהם (unit 6 of 8).
English: “Silver and gold on them” — non-Jews who worship mountains and hills: the mountains themselves are permitted, and what is upon them is forbidden, as it is said, “You shall not covet the silver and gold on them and take it for yourself.”
Custom (mountains vs. what is on them)
Natural landscape worshipped as deity is not forbidden as substance; artificial adornments on it are.
