Matthew Poole and continuators on Acts 19:33

33 And they drew Alexander out of the multitude, the Jews putting him forward. And Alexander beckened with the hand, and would have made his defence unto the people.

Where he could not be seen and heard, unto some more convenient place, from whence he might make a vindication or defence for them; and that most likely in behalf of the Iews, who were equally obnoxious to the rage of the people for being against their Idolatry, as the Christians were. This Alexander is thought to have been that Alexander of whom we read, 1 Tim. 1.20. 2 Tim. 4.14. tho some think that this was another of that name.

To procure silence; as Chap. 12.17.
