Someone in my local Bible study said that Mark 12:13-17 is a reference to the Fiscus Judaicus. How can I use Logos Bible Software to find the victims of the fiscus Judaicus in the biblical text? I tried a Bible search but I am not sure how to formulate it. It may not have even been alive during the time but I suspect it was. Cohen, Shaye J. D. (October 10, 2012). "The Fiscus Judaicus and the Parting of the Ways". Biblical Archaeology Society helped to explain it a bit.
5. The Jewish communities possessed the right to levy taxes upon their members (this is the meaning of the word αὐτοτελής as applied to the Jewry in Alexandria) to defray the common expenses, especially in connection with the maintenance of the synagogue. Details as to the character of these taxes are wanting; but they seem to a large extent to have served the purpose of supplementing the voluntary contributions, as is attested by numerous inscriptions. The principal levy, dictated by the demands of the community, was that of the didrachma, an annual poll-tax of a Tyrian half-shekel (=2 Greek drachmas), payable by each adult male-member, and destined to sustain the treasury of the Temple in Jerusalem. The amounts collected from the several communities were then combined, and, through special confidential envoys, were sent, either in the original coins or in a converted form, to Jerusalem (Philo, “Legatio ad Caium,” § 23). This practise, which in time involved a considerable export of gold to Palestine, met with a vigorous opposition on the part of the Greek cities; while the Roman government also at first assumed a hostile attitude toward it. Under the republic the Senate, alarmed at the annual amount of gold sent by the Italian communities, several times prohibited all exportation of this metal, and the propretor Flaccus confiscated the sums collected in Asia Minor for the Temple (Cicero, “Pro Flacco,” xxviii.). Later, edicts of Cæsar, confirmed by Augustus, again authorized the practise, both as to Rome and the provinces; and when the cities of Asia Minor and of Cyrene attempted to oppose it, Agrippa intervened in favor of the Jews, while a series of edicts broke the resistance of the Greek cities (14 B.C.; “Ant.” xiv. 6, §§ 2–7; Philo, l.c. § 40).
After the fall of the Temple (70), the Roman government, instead of simply abolishing a tax which had no further object, decided to impose it for the benefit of the treasury of Jupiter Capitolinus in Rome (“B. J” vii. 6, § 6; Dio Cassius, lxvi. 7). This was the origin of the “fiscus Judaicus,” a tax doubly irksome to the Jews; and the collection of which by the procurators ad hoc (“procuratores ad capitularia Judæorum”), according to the registers containing the names of those circumcised, was accompanied by the most odious vexations, notably under Domitian (Suetonius, “Domitian,” 12). Nerva abolished the abuses and delations (there are still extant bronzes bearing the legend FISCI IVDAICI CALVMNIA SVBLATA), but not the tax itself, which was still collected in the time of Origen (“Epistola ad Afric.” 14). There is reason to believe that it was gradually replaced by indefinite exactions, often levied without notice—a system of assessment which was finally abolished by Julian (Julian. Ep. 25; the text is obscure and doubtful). On this occasion, Julian destroyed the fiscal registers in which the names of the Jews were inscribed.
