Malachi 3:6

4Then the offering of Judah and Jerusalem will be pleasant to the LORD as in the days of old and as in ancient years.

5I will come near to you to judgment. I will be a swift witness against the sorcerers, against the adulterers, against the perjurers, and against those who oppress the hireling in his wages, the widow, and the fatherless, and who deprive the foreigner of justice, and don’t fear me,” says the LORD of Armies.

6“For I, the LORD, don’t change; therefore you, sons of Jacob, are not consumed.

7From the days of your fathers you have turned away from my ordinances and have not kept them. Return to me, and I will return to you,” says the LORD of Armies. “But you say, ‘How shall we return?’

8Will a man rob God? Yet you rob me! But you say, ‘How have we robbed you?’ In tithes and offerings.
