Malachi 3:5, 18

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 the false swearers, and against those that oppress the hireling in his wages, the widow, and the fatherless, and that turn aside the sojourner from his right, and fear not me, saith Jehovah of hosts.

Then shall ye return and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.
