Malachi 2:3-5

Behold, I will rebuke your offspring, and spread dung on your faces, the dung of your offerings, and you shall be taken away with it. So shall you know that I have sent this command to you, that my covenant with Levi may stand, says the LORD of hosts. My covenant with him was one of life and peace, and I gave them to him. It was a covenant of fear, and he feared me. He stood in awe of my name.
