"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.
"I am the LORD, and I do not change. That is why you descendants of Jacob are not already completely destroyed.

"Should people cheat God? Yet you have cheated me!" But you ask, 'What do you mean? When did we ever cheat you?'" You have cheated me of the tithes and offerings due to me.
You are under a curse, for your whole nation has been cheating me.
Bring all the tithes into the storehouse so there will be enough food in my Temple. If you do," says the LORD Almighty, "I will open the windows of heaven for you. I will pour out a blessing so great you won't have enough room to take it in! Try it! Let me prove it to you!
Your crops will be abundant, for I will guard them from insects and disease. Your grapes will not shrivel before they are ripe," says the LORD Almighty.
