 Polqar’s main work ʿEzer ha-Dat is comprised of five treatises. In the opening treatise, Polqar argues for the primacy of Jewish Law over other existing religious laws. For him, the Torah is the best law, and Moses, the lawgiver, is the paramount leader. Together, they provide Jewish believers with the necessary groundwork for attaining their ultimate purpose: the world to come. In this treatise Polqar highlights particular themes, such as the exile and its meaning, faith in the messiah’s ultimate arrival, Talmudic methodology and its authority, and how to interpret the words of the Sages. The choice of these themes seems to have been motivated by the Christians having made use of them in order to argue for the superiority of Christianity over Judaism.
