1 Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to this temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts.
2 But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner's fire, and like fullers' soap:
3 And he shall sit as a refiner and purifer 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.
