Malachi 2:3-7

ISV(i) 3 Look! I’m rebuking your descendants because of you, and I’ll spread waste on your faces, the waste of your festival sacrifices, and you will be carried off with it.
4 “You will know that I sent this commandment to you in order to continue my covenant with Levi,” says the LORD of the Heavenly Armies. 5 “My covenant with him was for life and peace, and I gave the commandments to him so he would fear me. He did fear me as he stood in my presence. 6 True teachings were in his mouth, and falsehood was not found on his lips. He walked with me peacefully and righteously, and he turned many from sin. 7 For the lips of a priest should preserve knowledge, and people should seek instruction from his mouth, because he’s the messenger of the LORD of the Heavenly Armies.
