uW Translation Notes:

Note 1 topic: figures-of-speech / rquestion

οὐκ ἄρα σὺ εἶ ὁ Αἰγύπτιος, ὁ πρὸ τούτων τῶν ἡμερῶν, ἀναστατώσας καὶ ἐξαγαγὼν εἰς τὴν ἔρημον τοὺς τετρακισχιλίους ἄνδρας τῶν σικαρίων

not (Some words not found in SR-GNT: οὐκ Ἄρα σύ εἶ ὁ Αἰγύπτιος ὁ πρό τούτων τῶν ἡμερῶν ἀναστατώσας καί ἐξαγαγών εἰς τήν ἐρῆμον τούς τετρακισχιλίους ἄνδρας τῶν σικαρίων)

The commander is using the question form to emphasize the conclusion he has drawn about Paul. Jews who spoke Greek typically came from somewhere outside of Palestine, and since Paul seems to be someone whom the Jews in Jerusalem consider to be very dangerous, the commander concludes that he must be the Egyptian he knows about. If you would not use the question form for this purpose in your language, you could translate this as a statement or an exclamation. Alternate translation: [Then you must not be the Egyptian who before these days revolted and led the 4,000 men of the Assassins into the wilderness!]

Note 2 topic: translate-transliterate

τῶν σικαρίων

¬the ˱of˲_the assassins

The term Sicarii is a Latin word. Luke spells it out using Greek letters so his readers will know how it sounds. The term means an assassin and it comes from the Latin word for a dagger. In this context, it refers to a group of Jewish rebels who carried daggers under their robes and killed Romans and people who supported the Romans. In your translation, you could spell this the way it sounds in your language, or you could use a term with the same meaning. Alternate translation: [of the Assassins]
