Leviticus 22:21-33

Whoever offers a sacrifice of peace offerings to the LORD to fulfill a special vow to the LORD or as a freewill offering from the herd or from the flock, it must be perfect to be accepted; there shall be no blemish in it. Animals that are blind or fractured or mutilated, or have a sore or a running wound or an itch or scabs, you shall not offer to the LORD nor make an offering of them by fire on the altar to the LORD. For a freewill offering you may offer either a bull or a lamb which has an overgrown or stunted member (deformity), but for [the payment of] a vow it will not be accepted. You shall not offer to the LORD any animal which has its testicles bruised or crushed or torn or cut off, or sacrifice it in your land. Nor shall you offer as the food of your God any such [animals obtained] from a foreigner, because their corruption and blemish makes them unfit; there is a defect in them, they shall not be accepted for you.’ ” Then the LORD spoke to Moses, saying, “When a bull or a sheep or a goat is born, it shall remain for seven days with its mother; and after the eighth day it shall be accepted as an offering by fire to the LORD. And whether [the mother] is a cow or a sheep, you shall not kill both it and its young in one day. When you sacrifice an offering of thanksgiving to the LORD, you shall sacrifice it so that you may be accepted. It shall be eaten on the same day; you shall leave none of it until the next morning; I am the LORD. So you shall keep My commandments and do them; I am the LORD. “You shall not profane My holy name [using it to honor an idol, or treating it with irreverence or contempt or as a byword]; but I will be sanctified (set apart as holy) among the Israelites. I am the LORD, who sanctifies and declares you holy, who brought you out of the land of Egypt to be your God; I am the LORD.”
