Smith's Bible Dictionary (1863)
(fixed), according to the general opinion of the Jews, was the queen of Nineveh at the time when Nahum delivered his prophecy. (Nahum 2:7) (B.C. about 700.) The moderns follow the rendering in the margin of our English Bible—“that which was established.” Still it is not improbable that after all Huzzab may really be a proper name. It may mean “the Zab country,” or the fertile tract east of the Tigris, watered by the upper and lower Zab
rivers.
Hastings' Dictionary of the Bible (1898)
HUZ'ZAB appears in the A.V. as a proper name, a queen of Nineveh in the days of Nahum, Nah 2:7. Many scholars, however, take it as a geographical term meaning "the country of Zab." But perhaps it is best regarded as a part of speech, and read: "And it is decreed."
