"Abraham, Isaac and Jacob, known as the Patriarchs, are both the physical and spiritual ancestors of Judaism. They founded the religion now known as Judaism, and their descendants are the Jewish people. Of course, technically, it is incorrect to refer to Abraham, Isaac and Jacob as Jews, because the terms "Jew" and "Judaism" were not used generally to refer to this nation until hundreds of years after their time; nevertheless, for convenience and in accordance with common practice, I will use these terms.
