Mishnayos Temurah Perek 1 Mishnah 6

The birds sacrificed as offerings, i.e., doves and pigeons, and the meal offerings do not render non-sacred items exchanged for them substitutes, as only the term “an animal” is stated with regard to substitution, in the verse: “And if he substitutes an animal for an animal” (Leviticus 27:10). A consecrated animal belonging to the community or to partners does not render a non-sacred animal exchanged for it a substitute, as it is stated in the same verse: “He shall neither exchange it nor substitute it.” One derives from the singular pronoun in the verse that an individual renders a non-sacred animal a substitute, but the community and partners do not render a non-sacred animal a substitute. Items consecrated for Temple maintenance do not render non-sacred items exchanged for them substitutes. Rabbi Shimon said: The fact that animals belonging to the community or partners do not render animals exchanged for them substitutes is derived as follows: The animal tithe was included in the category of all offerings, and why was it singled out in the verse: “And all the tithe of the herd or the flock, whatever passes under the rod, the tenth shall be sacred unto the Lord. He shall not inquire whether it is good or bad, neither shall he substitute for it; and if he substitutes it, then both it and that for which it is substituted shall be sacred” (Leviticus 27:32–33)? Rabbi Shimon explains: It was singled out to juxtapose substitution to the animal tithe, to tell you: Just as the animal tithe is brought exclusively as an individual offering, so too, all offerings that render their substitutes sacred are individual offerings, excluding communal offerings and the offerings of partners from the halakha of substitution. And just as the animal tithe is an offering sacrificed on the altar, so too, all offerings that render their substitutes sacred are offerings sacrificed on the altar, excluding items consecrated for Temple maintenance from the halakha of substitution.
