Tractate Bekhorot in the Mishnah, Tosefta, and Talmud interpreted the laws of the firstborn in 12–13; and and and Elsewhere, the Mishnah drew from that money in exchange for a firstborn donkey could be given to any Kohen; that if a person weaves the hair of a firstborn donkey into a sack, the sack must be burned; that they did not redeem with the firstborn of a donkey an animal that falls within both wild and domestic categories (a "koy"); and that one was prohibited to derive benefit in any quantity at all from an unredeemed firstborn donkey. And elsewhere, the Mishnah taught that before the Israelites constructed the Tabernacle, the firstborns performed sacrificial services, but after the Israelites constructed the Tabernacle, the Priests (, "Kohanim") performed the services.
