Leviticus 22:21

“Speak to Aaron, and to his sons, and to all the children of Israel, and say to them, ‘Whoever is of the house of Israel, or of the foreigners in Israel, who offers his offering, whether it is any of their vows or any of their free will offerings, which they offer to the LORD for a burnt offering:

that you may be accepted, you shall offer a male without defect, of the bulls, of the sheep, or of the goats.

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

You 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.

Either 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.

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