Malachi 3:1-5 - Yahweh's Messenger Is Coming
1 Behold, I send my messenger! He will prepare the way before me. Seek Jehovah! He will suddenly come to his Temple along with the messenger of the covenant. He is one you desire, behold, he comes, said Jehovah of Hosts. 2 Who can endure the day of his coming? Who can stand when he appears? He is like a refiner's fire and like laundry soap (the lye of laundrymen). 3 He will sit as a refiner and purifier of silver. He will purify the sons of Levi, and refine them like gold and silver. Then they will offer to Jehovah offerings in righteousness. 4 The offerings of Judah and Jerusalem will be pleasant to Jehovah like it was in the old days, in ancient years.
5 I will approach you people for judgment! I will be a swift witness against the sorcerers, the adulterers and those acting fraudulently with the wages of the worker, the widow and the fatherless. I will be a speedy witness against those who swear falsely and take advantage of the stranger, and do not show me reverence, said Jehovah of Hosts.
