UZ, a region and tribe mentioned in Scripture (Job. i. 1, Jer. xxv. 20, Lam. iv. 21), and now generally supposed to have occupied the south of Arabia Deserta, between Idumea, Palestine, and the Euphrates. The tribe seems to have been descended from Uz the son of Aram (Gen. x. 23), although its origin is by some referred to Huz the son of Nahor (Gen. xxii. 21), or to Uz the Horite, son of Dishan (Gen. xxxvi. 28).
