Leviticus 22:19-27

you shall offer of your own free will a male without blemish from the cattle, from the sheep, or from the goats. Whatever has a defect, you shall not offer, for it shall not be acceptable on your behalf. And whoever offers a sacrifice of a peace offering to the LORD, to fulfill his vow, or a freewill offering from the cattle or the sheep, it must be perfect to be accepted; there shall be no defect in it. Those that are blind or broken or maimed, or have an ulcer or eczema or scabs, you shall not offer to the LORD, nor make an offering by fire of them on the altar to the LORD. Either a bull or a lamb that has any limb too long or too short you may offer as a freewill offering, but for a vow it shall not be accepted. ‘You shall not offer to the LORD what is bruised or crushed, or torn or cut; nor shall you make any offering of them in your land. Nor from a foreigner’s hand shall you offer any of these as the bread of your God, because their corruption is in them, and defects are in them. They shall not be accepted on your behalf.’ ” And the LORD spoke to Moses, saying: “When a bull or a sheep or a goat is born, it shall be seven days with its mother; and from the eighth day and thereafter it shall be accepted as an offering made by fire to the LORD.
