The lyric is “Long live our noble King.” It belongs to “God Save the King,” the British royal anthem used in its male-monarch form.
The phrase expresses a traditional blessing for the sovereign: “long live” is a wish for the monarch’s continued life and reign, while “noble King” supplies the canonical completion. The song’s wording has deep roots in royal proclamations and biblical language, including passages associated with the First Book of Kings.
The anthem’s history is not completely fixed. A version was published in The Gentleman’s Magazine in 1745, and different verses have circulated over time. When a queen reigns, the wording changes to “God save the Queen” and “Long live our noble Queen.” That alternate form explains why “Queen” may look tempting, but under the current male-monarch wording, “King” is the single expected answer.
