Footnote

a “Tax collectors were especially despised by the Jewish population of Palestine for several reasons: (1) they collected money for the foreign power that occupied the land of Israel, thus indirectly giving support to this outrage; (2) they were notoriously unscrupulous, growing wealthy at the expense of others of their own people; and (3) their work involved them in regular contact with Gentiles, rendering them ritually unclean. Contempt for tax collectors is found both in the N[ew] T[estament] and the rabbinic literature . . . According to the latter, hatred was to be extended even to the family of the tax collector.”​—The International Standard Bible Encyclopedia.
