Acts 19:13 - Clarke's commentary and critical notes on the Bible

Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. Certain of the vagabond Jews, exorcists - Τινες απο των περιερχομενων Ιουδαιων εξορκιϚων; Certain of the Jews who went about practicing exorcisms. Vagabond has a very bad acceptation among us; but, literally, vagabundus signifies a wanderer, one that has no settled place of abode. These, like all their countrymen, in all places, went about to get their bread in what way they could; making trial of every thing by which they could have the prospect of gain. Finding that Paul cast out demons through the name of Jesus, they thought, by using the same, they might produce the same effects; and, if they could, they knew it would be to them an ample source of revenue; for demoniacs abounded in the land.
