1. Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom you seek, shall suddenly come to his temple, even the messenger of the covenant, whom you delight in: behold, he shall come,
2. But who may endure the day of his coming? and who shall stand when he appears? for he is like a refiner's fire, and like fullers' soap:
3. And he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.
