Malachi 3:4

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

2 But who may abide the day of his coming? and who shall stand when he appeareth? for he [is] like a refiner's fire, and like fuller's soap.

3 And he shall sit [as] a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer to the LORD an offering in righteousness.

4 Then shall the offering of Judah and Jerusalem be pleasant to the LORD, as in the days of old, and as in former years.

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

6 For I [am] the LORD, I change not; therefore ye sons of Jacob are not consumed.

7 Even from the days of your fathers ye have gone away from my ordinances, and have not kept [them]. Return to me, and I will return to you, saith the LORD of hosts. But ye said, In what shall we return?
