list the duties of the satraps of the persian government
Satrap The satrap was in charge of the land that he owned as an administrator, and found himself surrounded by an all-but-royal court; he collected the taxes, controlled the local officials and the subject tribes and cities, and was the supreme judge of the province before whose "chair" (Nehemiah 3:7) every civil and criminal case could be brought. He was responsible for the safety of the roads (cf. Xenophon), and had to put down brigands and rebels.
