Malachi 1:7-8

1:7 You are offering improper sacrifices on my altar, yet you ask, ‘How have we offended you?’ By treating the table of the Lord as if it is of no importance! 1:8 For when you offer blind animals as a sacrifice, is that not wrong? And when you offer the lame and sick, is that not wrong as well? Indeed, try offering them to your governor! Will he be pleased with you or show you favor?” asks the Lord who rules over all.

Malachi 1:12-14

1:12 “But you are profaning it by saying that the table of the Lord is common and its offerings despicable. 1:13 You also say, ‘How tiresome it is.’ You turn up your nose at it,” says the Lord who rules over all, “and instead bring what is stolen, lame, or sick. You bring these things for an offering! Should I accept this from you?” asks the Lord. 1:14 “There will be harsh condemnation for the hypocrite who has a valuable male animal in his flock but vows and sacrifices something inferior to the Lord. For I am a great king,” says the Lord who rules over all, “and my name is awesome among the nations.”
