At that time, two types of currency circulated in Palestine: secular and sacred. The secular currency was a Roman coin bearing the likeness of Caesar along with an inscription, widely used by the Jewish people in their commerce and for tax payments to Rome. Conversely, the Jewish shekel was regarded as sacred, utilized for the annual temple tax that every Jew was obligated to pay, regardless of their location.
The Jewish population viewed themselves as subjects of God alone, hence they believed that their tax obligations were solely to Him, specifically for the temple in Jerusalem. They considered any other tribute to be illegitimate, as it would imply subjugation to a king other than God, rendering them as captives of Gentile authority. This matter was likely of significant interest to the followers of Jesus, who were loyal to Him.
If He stated that paying taxes to Caesar was lawful, He risked alienating the people, who despised the tax. Conversely, if He declared the tax unlawful, He would provide grounds for His prosecution by Pilate. When the Pharisees approached Jesus regarding the tax, they pretended to be earnest disciples and sought to flatter Him with praise: "Teacher, we recognize your righteousness and your unwavering commitment to truth, regardless of its reception by others, including earthly rulers; you are unafraid to correct those in wrongdoing since you genuinely teach the path of God. Therefore, please tell us your position: Is it lawful to pay taxes to Caesar, or is it unlawful? Are we not, by paying this tax, becoming servants to a pagan king? Please enlighten us on whether we should remit this tax or abstain from it."
