About whom is the prophecy and does it apply to our time?
Malachi 2:4 Then you will know that I have given this commandment to you so that my covenant with Leʹvi may continue,” says Jehovah of armies. 5 “My covenant with him was one of life and of peace, which I gave to him, along with fear. He feared me, yes, he stood in awe of my name. 6 The law of truth was in his mouth, and no unrighteousness was found on his lips. He walked with me in peace and in uprightness, and he turned many back from error. 7 For the lips of a priest should safeguard knowledge, and people should seek the law from his mouth, because he is the messenger of Jehovah of armies.
Malachi 3:1…And suddenly the true Lord, whom you are seeking, will come to his temple; and the messenger of the covenant will come, in whom you take delight. Look! He will certainly come,” says Jehovah of armies. 2 “But who will endure the day of his coming, and who will be able to stand when he appears? For he will be like the fire of a refiner and like the lye of laundrymen. 3 And he will sit as a refiner and cleanser of silver and will cleanse the sons of Leʹvi; and he will clarify them like gold and like silver, and they will certainly become to Jehovah people presenting a gift offering in righteousness.
