HUZZAB - H>@ - (fixed), according to the general opinion of the Jews, was the queen of Nineveh at the time when Nahum delivered his prophecy. kjv@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.
