Leviticus 22:8, 19-23

He may not eat an animal that has died a natural death or has been torn apart by wild animals, for this would defile him. I am the LORD.

you will be accepted only if your offering is a male animal with no defects. It may be a bull, a ram, or a male goat. Do not present an animal with defects, because the LORD will not accept it on your behalf. “If you present a peace offering to the LORD from the herd or the flock, whether it is to fulfill a vow or is a voluntary offering, you must offer a perfect animal. It may have no defect of any kind. You must not offer an animal that is blind, crippled, or injured, or that has a wart, a skin sore, or scabs. Such animals must never be offered on the altar as special gifts to the LORD. If a bull or lamb has a leg that is too long or too short, it may be offered as a voluntary offering, but it may not be offered to fulfill a vow.
