Acts 19:13

vagabond Jews--simply, "wandering Jews," who went from place to place practicing exorcism, or the art of conjuring evil spirits to depart out of the possessed. That such a power did exist, for some time at least, seems implied in Mat 12:27. But no doubt this would breed imposture; and the present case is very different from that referred to in Luk 9:49-50. We adjure you by Jesus whom Paul preacheth--a striking testimony to the power of Christ's name in Paul's mouth.

The preachers of the gospel were sent forth to carry on a war against Satan, and therein Christ went forth conquering and to conquer. The casting of evil spirits out of those that were possessed was one instance of Christ's victory over Satan; but, to show in how many ways Christ triumphed over that great enemy, we have here in these verses two remarkable instances of the conquest of Satan, not only in those that were violently possessed by him, but in those that were voluntarily devoted to him. I. Here is the confusion of some of Satan's servants, some vagabond Jews, that were exorcists, who made use of Christ's name profanely and wickedly in their diabolical enchantments, but were made to pay dearly for their presumption. Observe, 1. The general character of those who were guilty of this presumption. They were Jews, but vagabond Jews, were of the Jewish nation and religion, but went about from town to town to get money by conjuring. They strolled about to tell people their fortunes, and pretended by spells and charms to cure diseases, and bring people to themselves that were melancholy or distracted. They called themselves exorcists, because in doing their tricks they used forms of adjuration, by such and such commanding names. The superstitious Jews, to put a reputation upon these magic arts, wickedly attributed the invention of them to Solomon. So Josephus (Antiq. 8.45-46) says that Solomon composed charms by which diseases were cured, and devils driven out so as never to return; and that these operations continued common among the Jews to his time. And Christ seems to refer to this (Mat 12:27), By whom do your children cast them out? 2. A particular account of some at Ephesus that led this course of life and came thither in their travels; they were seven sons of on…

19:13-16 Paul’s effectiveness is contrasted with the impotence of the traveling Jewish exorcists, who used the name of Jesus as though it were magical but did not have a relationship with him or the indwelling power of the Holy Spirit (cp. Matt 12:27; Mark 9:38-39; Luke 9:49-50; 11:19).
