The Knesset is Israel’s legislature. The Knesset took its name and fixed its membership at 120 from the Knesset Hagedolah (Great Assembly), the representative Jewish council convened in Jerusalem by Ezra and Nehemiah in the 5th century B.C.E.
Members of Knesset (MKs) are elected every four years. The major function of the Knesset is to legislate laws and revise them as necessary. Additional duties include establishing a government, taking policy decisions, reviewing government activities, and electing the President of the State and the State Comptroller.
