Malachi 1:8-9

8You offer blind animals as a sacrifice to me. You know that is wrong. You offer to me animals that cannot walk or animals that are ill. That is also a wrong thing to do. You would not give gifts like that to your city's ruler. If you did, he would surely not accept them. He would not be happy with your gifts.’ That is what the Lord Almighty says.

9‘Now you ask me to be kind to you. You want me to forgive you. But when you offer unclean animals as gifts to me, I will not be happy with your gifts.’ That is what the Lord Almighty says.
