When he had read it (anagnou). Second aorist active participle of anaginwskw, to know again, to read. Of what province he was (ek poia eparceia estin). Tense of estin (is) retained in indirect question. Poia is strictly "of what kind of" province, whether senatorial or imperial. Cilicia, like Judea, was under the control of the propraetor of Syria (imperial province). Paul's arrest was in Jerusalem and so under the jurisdiction of Felix unless it was a matter of insurrection when he could appeal to the propraetor of Syria.
