Leviticus 22:20-28

²⁰But you shall not offer whatever has a defect, for it shall not be acceptable for you.

²¹Whoever offers a sacrifice of peace offerings to the LORD to accomplish a vow, or for a free will offering of the herd or of the flock, it shall be perfect to be accepted. It shall have no defect.

²²You shall not offer what is blind, is injured, is maimed, has a wart, is festering, or has a running sore to the LORD, nor make an offering by fire of them on the altar to the LORD.

²³Either a bull or a lamb that has any deformity or lacking in his parts, that you may offer for a free will offering; but for a vow it shall not be accepted.

²⁴You must not offer to the LORD that which has its testicles bruised, crushed, broken, or cut. You must not do this in your land.

²⁵You must not offer any of these as the bread of your God from the hand of a foreigner, because their corruption is in them. There is a defect in them. They shall not be accepted for you.’”

²⁶The LORD spoke to Moses, saying,

²⁷“When a bull, a sheep, or a goat is born, it shall remain seven days with its mother. From the eighth day on it shall be accepted for the offering of an offering made by fire to the LORD.

²⁸Whether it is a cow or ewe, you shall not kill it and its young both in one day.
