It has been said that the Torah is not a history book and her words are succinct. In addition to the "obvious" people and stories/events discussed in scripture, there are many others mentioned if only by name. Has Judaism ever considered the possibility that there were other great, G-d fearing people (or important events) who/which were not mentioned, even in passing, in the Torah and for what reason?
For example, is it possible that Abraham's neighbor, "Tzvi", three tents down, approached, equaled or excelled Abraham's greatness but was not mentioned, for whatever was G-d's reason, in the Torah? Obviously the Torah considers Moshe to be the greatest prophet ever. Is there, however, any evidence for or against the possibility that there existed during biblical times Torah-true prophets or leaders (or events) that Hashem did not elaborate upon in His torah? Put into another context, which Torah giants of the 19th and 20th centuries will be venerated 100 years from now? It is unlikely that they all will be remembered to the same degree. Some might be mentioned only in passing. Many will be forgotten. To sum up, Did the same thing happen in the Torah?
For purposes of this question, I am limiting reference only to the Tenakh, not "rejected" works such as pseudepigraphic, apocryphic and Dead Sea scrolls.
