Leviticus 22:19-27

for you to be accepted—it must be a male without defect from the cattle, the sheep, or the goats. Whatever has a defect, you shall not offer, for it will not be accepted for you. When someone offers a sacrifice of peace offerings to the LORD to fulfill a special vow or for a voluntary offering, of the herd or of the flock, it must be without defect to be accepted; there shall be no defect in it. Those that are blind, fractured, maimed, or have a wart, a festering rash, or scabs, you shall not offer to the LORD, nor make of them an offering by fire on the altar to the LORD. Now as for an ox or a lamb which has an overgrown or stunted member, you may present it as a voluntary offering, but for a vow it will not be accepted. Also anything with its testicles squashed, crushed, torn off, or cut off, you shall not offer to the LORD, nor sacrifice in your land, nor shall you offer any of these animals taken from the hand of a foreigner as the food of your God; for their deformity is in them, they have an impairment. They will not be accepted for you.’ ” Then the LORD spoke to Moses, saying, “When an ox or a sheep or a goat is born, it shall remain seven days with its mother, and from the eighth day on it will be considered acceptable as a sacrifice of an offering by fire to the LORD.
