Malachi 3:1-5

“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 of Heaven’s Armies. “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 bleaches clothes. He will sit like a refiner of silver, burning away the dross. He will purify the Levites, refining them like gold and 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 the past. “At that time I will put you on trial. I am eager to 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 of Heaven’s Armies.
