"Look! I am sending my messenger, and he will prepare the way before me. Then the Lord you are seeking will suddenly come to his Temple. The messenger of the covenant, whom you look for so eagerly, is surely coming," says the LORD Almighty.
"But who will be able to endure it when he comes? Who will be able to stand and face him when he appears? For he will be like a blazing fire that refines metal or like a strong soap that whitens clothes.
He will sit and judge like a refiner of silver, watching closely as the dross is burned away. He will purify the Levites, refining them like gold or silver, so that they may once again offer acceptable sacrifices to the LORD.
Then once more the LORD will accept the offerings brought to him by the people of Judah and Jerusalem, as he did in former times.
At that time I will put you on trial. I will be a ready witness against all sorcerers and adulterers and liars. I will speak against those who cheat employees of their wages, who oppress widows and orphans, or who deprive the foreigners living among you of justice, for these people do not fear me," says the LORD Almighty.
