Malachi 3:5

5 The Lord All-Powerful says, "Then I will come to you and judge you. I will be quick to testify against those who take part in evil magic, adultery, and lying under oath, those who cheat workers of their pay and who cheat widows and orphans, those who are unfair to foreigners, and those who do not respect me.

Malachi 3:5 Meaning and Commentary

Malachi 3:5

And I will come near to you to judgment
And so will manifestly appear to be the God of judgment they asked after, ( Malachi 2:17 ) this is not to be understood of Christ's coming to judgment at the last day, but of his coming to judge and punish the wicked Jews at the time of Jerusalem's destruction; for the same is here meant, who is spoken of in the third person before, and who will not be afar off; there will be no need to inquire after him, when he will come he will be near enough, and too near for them: and I will be a swift witness against the sorcerers;
not only a judge, but a witness; so that there will be no delay of judgment, or protracting or evading it, for want of witnesses of facts alleged; for the Judge himself, who is Christ, will be witness of them, he being the omniscient God, before whom all things are manifest. The Targum is,

``my Word shall be among you for a swift witness.''

Mention is made of "sorcerers", because there were many that used the magic art, enchantments, and sorceries, in the age of Christ and his apostles, and before the destruction of Jerusalem, even many of their doctors and members of the sanhedrim; (See Gill on Isaiah 8:19): and against the adulterers;
with whom that age also abounded; hence our Lord calls it an adulterous generation, ( Matthew 12:39 ) ( John 8:3-9 ) ( Romans 2:22 ) : and against false swearers;
who were guilty of perjury, and of vain oaths; who swore by the creatures, and not by the Lord, and to things not true; see ( Matthew 5:33-37 ) : and against those that oppress the hireling in [his] wages, the
widow, and the fatherless;
defrauding of servants of their wages, devouring widows' houses, and distressing the fatherless, were sins the Jews were addicted to in those times, as appears from ( James 1:27 ) ( 5:4 ) who wrote to the twelve tribes; and from what our Lord charges them with, ( Matthew 23:14 ) : and that turn aside the stranger [from his right];
and so Kimchi supplies it,

``that turn aside the judgment of the stranger;''

that do not do him justice in civil things; yea, persecuted those that became proselytes to the Christian religion: and fear not me, saith the Lord of hosts;
which was the root and cause of all their sins; irreverence of Christ, disbelief of him, and contempt of his Gospel.

Malachi 3:5 In-Context

3 Like someone who heats and purifies silver, he will purify the Levites and make them pure like gold and silver. Then they will bring offerings to the Lord in the right way.

4 And the Lord will accept the offerings from Judah and Jerusalem, as it was in the past.

5 The Lord All-Powerful says, "Then I will come to you and judge you. I will be quick to testify against those who take part in evil magic, adultery, and lying under oath, those who cheat workers of their pay and who cheat widows and orphans, those who are unfair to foreigners, and those who do not respect me.

6 "I the Lord do not change. So you descendants of Jacob have not been destroyed.

7 Since the time of your ancestors, you have disobeyed my rules and have not kept them. Return to me, and I will return to you," says the Lord All-Powerful. "But you ask, 'How can we return?'
