Malachi 1:13-14

13You also say, “It is too much trouble to serve the Lord.” You think that you are too important to serve me.’ That is what the Lord Almighty says. ‘You offer to me animals that cannot walk or that are ill. You have even robbed other people to get some of these animals. Do you think that I will accept these unclean animals from you? Will I be happy with them?’ That is what the Lord says.

14‘You may promise to offer to me a valuable male animal from among your sheep. But then you change your mind. Instead, you offer to me an animal that has no value. I will surely punish you when you cheat me like that. Remember that I am a great king. People of all nations in the world respect my name with fear.’ That is what the Lord Almighty says.
