Malachi 3:1-5

1Behold, I send my messenger, and he shall prepare the way before me; and the Lord whom ye seek will suddenly come to his temple, and the Angel of the covenant, whom ye delight in: behold, he cometh, saith Jehovah of hosts.

2But who shall endure the day of his coming? and who shall stand when he appeareth? For he will be like a refiner's fire, and like fullers' lye.

3And he shall sit [as] a refiner and purifier of silver; and he will purify the children of Levi, and purge them as gold and silver; and they shall offer unto Jehovah an oblation in righteousness.

4Then shall the oblation of Judah and Jerusalem be pleasant unto Jehovah, as in the days of old, and as in former years.

5And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against the false swearers, and against those that oppress the hired servant in [his] wages, the widow and the fatherless, and that turn aside the stranger [from his right], and fear not me, saith Jehovah of hosts.
