Acts 21:33

Then the chief captain came near
To the place where the Jews were beating Paul:

and took him
the Arabic version adds, "from them"; he rescued him out of their hands, as he himself says, ( Acts 23:27 ) .

And commanded him to be bound with two chains:
partly to appease the people, and partly to secure Paul; who, he supposed, had been guilty of some misdemeanour, which had occasioned this tumult; these two chains were put, one on one arm, and the other on the other arm; and were fastened to two soldiers, who walked by him, having hold on those chains, the one on his right hand, and the other on his left; and thus Agabus's prophecy in ( Acts 21:11 ) was fulfilled:

and demanded who he was;
or asked and inquired about him, who he was, of what nation he was, what was his character, business, and employment: this inquiry was made, either of the apostle himself, or of the people; and so the Arabic version renders it, "he inquired of them who he was"; also

and what he had done;
what crime he had been guilty of, that they used him in such a manner.
