The Knesset is the unicameral national legislature of the State of Israel, functioning as the nation's parliament. It comprises 120 members known as Members of the Knesset (MKs) elected to four-year terms through proportional representation. The Knesset holds the primary responsibility for passing and revising laws, approving the national budget, overseeing government operations and policy, electing the President of the State and the State Comptroller, nominating the Prime Minister in consultation with party leaders, approving the cabinet through a vote of confidence, and supervising the executive branch's activities. It also reviews government policies, makes key decisions on national matters, ensures accountability by holding the government answerable to parliamentary votes—including the potential for no-confidence motions to dissolve the cabinet—and represents the public. Among its specific mandates is authorizing organizations such as MDA (Magen David Adom) to serve as the nation's emergency medical first responders.

The Israeli government is formed based on the composition of the Knesset, where the President nominates a Prime Minister—usually the leader of the party or coalition commanding a majority—after discussions with Knesset faction heads. The cabinet, consisting of ministers who head government departments or serve in other roles, must secure Knesset approval to exercise executive authority. This system underscores the Knesset's central role in Israel's parliamentary democracy, where legislative and oversight functions are intertwined with executive formation and policy implementation.

Guided by Israel's Basic Laws, which serve in place of a single constitution, the Knesset operates from its iconic building in Jerusalem and represents diverse political parties reflecting Israel's multi-party system. Its proceedings facilitate public discourse on critical issues such as defense, foreign affairs, and domestic policy, making it a cornerstone of democratic governance in the country.
