Дварим 7:25 Галаха: Mishneh Torah, Foreign Worship and Customs, Mishneh Torah, Negative Mitzvot, Sefer HaChinukh & Sefer HaMitzvot

Wherein is the difference between an idol that belongs to an idolator and an idol that belongs to an Israelite? The idol of an idolater is forbidden property to enjoy aught thereof the moment it becomes an idol; it is said: "The graven images of their gods shall ye burn with fire" (Ibid. 7.25), the moment they became graven images it became a god to the idolater; but that of the Israelite does not become forbidden property until it is worshiped, as it is said: "And setteth up in secret" (Ibid. 27.15), until matters of secrecy will be done to it, which are its form of worship. But everything used in the service of idolatry, whether it belong to an idolator or to an Israelite, does not become forbidden property until they will be used during services to idolatry.⁴Ibid. 51–52a. C.

Idolatry, everything used in its service, and everything that is made for its sake, even a particle thereof renders everything it is mingled with and its identity lost therein forbidden property. For example? An idol which was mixed up with figures of beauty, even one in many thousands, all of it must be cast in the Dead Sea. Likewise if a cup of idolatry was mixed up with many other cups, or a piece of idolatrous meat in many pieces of other meat must be cast in the Dead Sea. Likewise if a heart-cut hide was mixed up with many other hides, all become forbidden property. If one did transgress and sold idolatry, or an article used in its service, or that which is made for its sake, even the proceeds thereof is forbidden property and a particle thereof renders all other things wherewith it is mixed up forbidden property, for it is as idolatry itself, even as it is said: "Nor take it unto thee, lest thou be desolate as itself" (Deut. 7.25)⁹The English translation of the Hebrew word “Harem”, both in the King James version and the 1917 edition of the Jewish Publication Society is wrong; Harem means a snare, as well as desolate, devout, isolated etc., but it never can mean “be esnared” or “be snared”. Neither does the Hebrew word “Komohu” mean either “therein” or “thereby”. G.; herefrom you deduct that everything you take in from idolatry from the things which are for its service, and from that which it is made for its use is like unto itself.¹⁰Abodah Zarah, 74b; Kiddushin, 58a. C.

Something which no human hand can seize that was worshiped, for instance mountains, cattle, or tree, although the object itself is permitted property, the decoration thereof is forbidden property, and whosoever enjoys aught thereof is striped; for it is said: "Thou shalt not covet the silver or gold that is on them" (Deut. 7.25). And, all decorations of idolatry are included among the things made for its service.¹⁰Ibid. 45a. C.
