IUBAL (Hebr.: Jābhāl; Greek: 'Ioušāh). – A Cainite, son of Lamech and Ada, “the father of all those who handle the lyre and the flute” (Gen. 4:21). That is, inventor of the kinnōr and the 'āghābh, rudimentary instruments—the former stringed, the latter a kind of flute—as shepherds make them from reed or other material.
In Gen. 4:21 ff., the emergence of the arts that constitute material civilization is described. Babylonian tradition, too, albeit in a different manner, attributes the origin of culture to the antediluvian generations.
