Leviticus 22:18-25

18‘Say this to Aaron, to his sons and to all the people. If any person gives a gift to the Lord,

19he must give a bull, a sheep or a goat. The gift may be for a promise, or to thank God for something or for a friendship offering. The animal must be perfect.

20They must not give any animal that is not perfect. The Lord will not accept that animal.

21When a person brings an animal to the Lord as a special gift, it must be perfect. If it is, God will accept it.

22A person must not give to the Lord an animal that cannot see. The animal must not have a skin disease. And pus must not be coming from its body. The person must not burn an animal to the Lord on the altar that is not perfect.

23A person may give a bull or a sheep with a body that is the wrong shape. He can use it as an offering to eat with his friends (friendship offering). But God will not take this animal as a gift for a promise. That gift must be perfect. You must not put on the altar an animal that is not perfect.

24A person must not give a gift to the Lord of an animal that has something wrong with its testicles.

25This rule is for Israel's people. You must not take animals from foreigners and then offer them to God as sacrifices. God will not accept them on your behalf, because animals like that are not perfect.’
