Malachi 3:1-3 Young's Literal Translation (YLT)
3 Lo, I am sending My messenger, And he hath prepared a way before Me, And suddenly come in unto his temple Doth the Lord whom ye are seeking, Even the messenger of the covenant, Whom ye are desiring, Lo, he is coming, said Jehovah of Hosts.
2 And who is bearing the day of his coming? And who is standing in his appearing? For he [is] as fire of a refiner, And as soap of a fuller.
3 And he hath sat, a refiner and purifier of silver, And he hath purified the sons of Levi, And hath refined them as gold and as silver, And they have been to Jehovah bringing nigh a present in righteousness.
