Leviticus 22:17-23

And the LORD spoke to Moses, saying, “Speak to Aaron and his sons, and to all the children of Israel, and say to them: ‘Whatever man of the house of Israel, or of the strangers in Israel, who offers his sacrifice for any of his vows or for any of his freewill offerings, which they offer to the LORD as a burnt offering— 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.
