Jeshurun

Smith's Bible Dictionary

Jesh'urun. (supremely happy). Jeshurun and, once by mistake in Authorized Version, as Jesurun, Isaiah 44:2, a symbolical name for Israel in Deuteronomy 32:15; Deuteronomy 33:5; Deuteronomy 23:26; Isaiah 44:2. It is most probably derived from a root, signifying "to be blessed." With the intensive termination, Jeshurun would then denote Israel, as supremely happy or prosperous, and to this signification the context in Deuteronomy 32:15 points.
