Leviticus 22:21-33

When anyone brings from the herd or flock a fellowship offering to the LORD to fulfill a special vow or as a freewill offering, it must be without defect or blemish to be acceptable. Do not offer to the LORD the blind, the injured or the maimed, or anything with warts or festering or running sores. Do not place any of these on the altar as a food offering presented to the LORD. You may, however, present as a freewill offering an ox or a sheep that is deformed or stunted, but it will not be accepted in fulfillment of a vow. You must not offer to the LORD an animal whose testicles are bruised, crushed, torn or cut. You must not do this in your own land, and you must not accept such animals from the hand of a foreigner and offer them as the food of your God. They will not be accepted on your behalf, because they are deformed and have defects.’ ” The LORD said to Moses, “When a calf, a lamb or a goat is born, it is to remain with its mother for seven days. From the eighth day on, it will be acceptable as a food offering presented to the LORD. Do not slaughter a cow or a sheep and its young on the same day. “When you sacrifice a thank offering to the LORD, sacrifice it in such a way that it will be accepted on your behalf. It must be eaten that same day; leave none of it till morning. I am the LORD. “Keep my commands and follow them. I am the LORD. Do not profane my holy name, for I must be acknowledged as holy by the Israelites. I am the LORD, who made you holy and who brought you out of Egypt to be your God. I am the LORD.”
