Malachi 3:6

2 But who can endure the day of His coming? And who can stand when He appears? For He will be like a refiner’s fire, like a launderer’s soap.

3 And He will sit as 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.

4 Then the offerings of Judah and Jerusalem will please the LORD, as in days of old and years gone by.

5 “Then I will draw near to you for judgment. And I will be a swift witness against sorcerers and adulterers and perjurers, against oppressors of the widowed and fatherless, and against those who defraud laborers of their wages and deny justice to the foreigner but do not fear Me,” says the LORD of Hosts.

6 “Because I, the LORD, do not change, you descendants of Jacob have not been destroyed.

7 Yet from the days of your fathers, you have turned away from My statutes and have not kept them. Return to Me, and I will return to you,” says the LORD of Hosts. “But you ask, ‘How can we return?’

8 Will a man rob God? Yet you are robbing Me! But you ask, ‘How do we rob You?’ In tithes and offerings.

9 You are cursed with a curse, yet you—the whole nation—are still robbing Me.

10 Bring the full tithe into the storehouse, so that there may be food in My house. Test Me in this,” says the LORD of Hosts. “See if I will not open the windows of heaven and pour out for you blessing without measure.
