All [consecrated animals] whose consecration preceded their blemish, or whose temporary blemish [preceded] their consecration, and a permanent blemish developed in them afterward, and they were redeemed —- are exempt from the laws of bechor and from the gifts [due the Kohen], and they do not revert to mundane status to [the extent that they may] be shorn and put to work, their offspring and their milk are prohibited after their redemption, one who slaughters them outside [the Temple Courtyard] is liable, they effect temurah, and if they died they must be buried.

[If] one receives animals at their fixed value from a non-Jew, the offspring are exempt [from the law of bechor], but the offspring of that offspring are liable. [If] he put the offspring in place of their mothers, the offspring of the offspring are exempt [from the law of bechor], but the offspring of the offspring of that offspring are subject [to it]. Rabban Shimon ben Gamliel says: Even up to ten generations, they are exempt [from the law of bechor], because the non-Jew has a lien on them.
