Mishnà su Esodo 13:28

These may be given to any priest:Devoted things (haramim); Firstlings; The redemption of the first born; The [lamb substituted as] ransom for the firstling of a donkey; The shoulder, the two cheeks and the maw; The first of the fleece; Oil [fit only] for burning; Consecrated food [which must be eaten] within the Temple; And bikkurim. Rabbi Judah prohibits bikkurim. Vetches of terumah: Rabbi Akiva permits, But the sages prohibit.

Rabbi Joshua and Rabbi Zadok testified concerning the redemption (lamb) of a firstborn donkey, that if it died, the priest receives nothing, Whereas Rabbi Eliezer says: the owner must bear the responsibility as with the five selas [in the case] of a [firstborn] son. But the Sages say: he bears no responsibility any more than in the case of the redemption of second tithes.

The peels and the blossom of the pomegranate, the nutshells, and fruit seeds the laws of sabbatical produce apply to them and to their money substitutes. The dyer may use them for himself, but he may not dye with them for a wage, since one may not engage in business with seventh year produce, or with first-born animals, or with terumah, or with nevelah, or with trefah, or with reptiles or with creeping things. One should not buy field-vegetables and sell them in the market. But he may gather them and have his son sell them on his behalf. If he gathered them for his own use, and some remains over, he may sell them.
