“The Men of the Great Assembly — in Hebrew, Anshei Knesset HaGedolah — was an unusual group of Jewish personalities who assumed the reigns of Jewish leadership between 410 BCE and 310 BCE.”
“In addition to insuring the accurate transmission of the Oral Torah, the Men of the Great Assembly decide which of the multitude of Jewish holy writings should be in the Bible. The Jewish people have produced hundreds of thousands of prophets (both men and women). Which of their writings should be preserved for future generations and which had limited applicability?”
“The Men of the Great Assembly make this decision and give us what is known as the Hebrew Bible today — or the Tanach. (Tanach is a Hebrew acronym which stands for Torah, Prophets, Writings.)”
