Malachi 3:1-3

1“See, I am going to send my messenger, and he will clear the way before me. Then the Lord you seek will suddenly come to his temple, the Messenger of the covenant you delight in — see, he is coming,” says the Lord of Armies.

2But who can endure the day of his coming? And who will be able to stand when he appears? For he will be like a refiner’s fire and like launderer’s bleach.

3He will be like a refiner and purifier of silver; he will purify the sons of Levi and refine them like gold and silver. Then they will present offerings to the Lord in righteousness.
