And I will come near to you to judgment,.... And so will manifestly appear to be the God of judgment they asked after, Mal 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.'
