וַתִּרְאוּ֙ אֶת־שִׁקּ֣וּצֵיהֶ֔ם וְאֵ֖ת גִּלֻּלֵיהֶ֑ם עֵ֣ץ וָאֶ֔בֶן כֶּ֥סֶף וְזָהָ֖ב אֲשֶׁ֥ר עִמָּהֶֽם׃
and ye have seen their detestable things, and their idols, wood and stone, silver and gold, which were with them—
Rashi on Deuteronomy
ותראו את שקוציהם AND YE HAVE SEEN THEIR ABOMINABLE THINGS — Idols are so termed because they are loathsome like unclean things that are held in abomination.
Rabbeinu Bahya
ותראו את שקוציהם...עץ ואבן, “you have seen their detestable idols, wood and stone, silver and gold.” The former were on display openly; the latter — due to their value and the owners being afraid of theft — were kept inside their homes (Tanchuma Nitzavim 3).
Siftei Chakhamim
Those of wood and stone, you saw in the open, etc. Rashi is explaining why the verse altered its wording and wrote you observed regarding wood and stone, but does not write you observed regarding gold and silver.
