Am HaSefer - People of The Book

In Judaism the term "People of the Book" (Hebrew: עם הספר, Am HaSefer) was used to refer specifically to the Jewish people and the Torah, and to the Jewish people and the wider canon of written Jewish law (including the Mishnah and the Talmud). Adherents of other Abrahamic religions, which arose later than Judaism, were not added As such, the appellation is accepted by Jews as a reference to an identity rooted fundamentally in Torah.

Nehemiah 8:1-3
(1) all the people gathered together at the square in front of the Water Gate. They asked Ezra the scribe to bring the book of the law of Moses that the L-RD had given Israel. (2) On the first day of the seventh month, Ezra the priest brought the law before the assembly of men, women, and all who could listen with understanding. (3) While he was facing the square in front of the Water Gate, he read out of it from daybreak until noon before the men, the women, and those who could understand. All the people listened attentively to the book of the law.
