Malachi 3:5

And I will come near to you to judgment, namely, the judgment of wrath upon the wicked; and I will be a swift witness against the sorcerers, the transgressors of the First and Second Commandments, and against the adulterers, those disregarding the Sixth Commandment, and against false swearers, with reference both to the Second and the Eighth Commandments, and against those that oppress the hireling in his wages, by withholding them altogether or by underpaying him, the widow, and the fatherless, as being without a natural protector, and that turn aside the stranger from his right, Cf Deuteronomy 27:19, and fear not Me, saith the Lord of hosts, this last point indicating the source of all iniquity lack of the fear of the Lord.
