Malachi 3:1-3 Darby Translation (DARBY)
3 Behold, I send my messenger, and he shall prepare the way before me; and the Lord whom ye seek will suddenly come to his temple, and the Angel of the covenant, whom ye delight in: behold, he cometh, saith Jehovah of hosts.
2 But who shall endure the day of his coming? and who shall stand when he appeareth? For he will be like a refiner's fire, and like fullers' lye.
3 And he shall sit [as] a refiner and purifier of silver; and he will purify the children of Levi, and purge them as gold and silver; and they shall offer unto Jehovah an oblation in righteousness.
