신명기 12:15 미슈나 참조: Mishnah Bekhorot, Mishnah Temurah & Mishnah Chullin

If [a portion of] the hair of a blemished first born fell out and he placed it in the window, and then he slaughtered the animal, Akavya ben Mahalalel allows it. But the sages forbid it, the words of Rabbi Judah. Rabbi Yose said to him: Akavya ben Mahalalel did not allow [only] in this case, but [even] in the case where the hair of a blemished first born which fell out and he placed it in the window, and the animal died subsequently, [even] in this case Akavya ben Mahalalel allows, but the sages forbid. If the wool of a first born is hanging loose, that part which appears [on a level] with [the rest of] the wool is permitted, whereas that which does not appear [on a level] with [the rest of] the wool is forbidden.

There are [laws] which apply to dedications for the altar which do not apply to dedications for repairs of the Temple, and there are [laws] which apply to dedications for the repairs of the Temple which do not apply to dedications for the altar.Dedications for the altar effect a substitute; They are subject to the laws of piggul, remnant and ritual uncleanness; Their offspring and milk are forbidden [even] after their redemption; If one kills them outside [the Temple] he is guilty; And wages are not paid from them to artisans, Which is not the case with dedications for temple repairs.

All consecrated animals whose permanent physical blemish preceded their consecration and were then redeemed: Are subject to the law of the firstling and to the priestly gifts, And when they become like hullin [by being redeemed] they may be shorn and may be put to work. And their young and their milk are permitted after they have been redeemed. And he who slaughtered them outside the sanctuary is not liable. And they do not render what is substituted for them [holy]. And if they died they may be redeemed, except for the firstling and the tithe of cattle. All [consecrated animals] whose consecration preceded their permanent, or their impermanent blemish [preceded] their consecration and subsequently they contracted a permanent blemish, and they were redeemed: Are exempt from the law of the firstling, and from priestly gifts; And they are not like unconsecrated animals to be shorn or put to work; And [even] after they have been redeemed their young and their milk are forbidden; And he who slaughtered them outside the sanctuary is liable; And they render what was substituted for them [holy], And if they died they must be buried.
