Leviticus 22:21-23

New Century Version

²¹ “‘If someone brings a fellowship offering to the Lord, either as payment for a special promise the person has made or as a special gift the person wants to give the Lord, it might be from the herd or from the flock. But it must be healthy, with nothing wrong with it, so that it will be accepted. ²² You must not offer to the Lord any animal that is blind, that has broken bones or is crippled, that has running sores or any sort of skin disease. You must not offer any animals like these on the altar as an offering by fire to the Lord.

²³ “‘If an ox or lamb is smaller than normal or is not perfectly formed, you may give it as a special gift to the Lord; it will be accepted. But it will not be accepted as payment for a special promise you have made.
