Brunetto Quilici's book, written in 1927, analyzes the financial evolution of the Jewish people from the nomadic period to the Roman era, examining the different forms of taxation, the income and expenditure of the kingdom, wars, and the role of priests and Levites. The issue of the diaspora is then addressed, analyzing the causes of the reluctance of the Jews to pay tribute to foreigners and how this influenced their history. The text is rich in historical, biblical and archaeological references.
