(Heb. Yubal', יוּבָל, prob. for יוּבֶל, jubilee, i.e. music Sept. Ι᾿ουβάλ ), Lamech's second son by Adah, of the line of Cain; described as the inventor of the כּנּור, kinnor, and the עוּגָב , ugab, rendered in our version "the harp and the organ," but perhaps more properly "the lyre and mouth-organ," or Pandaean pipe (Genesis 4:21). See Music. B.C. prob. cir. 3490. According to Josephus (Ι᾿ούβαλος, Ant. 1, 2, 2), "he cultivated music, and invented the psaltery and cithara." Some have compared him with the Apollo of heathen mythology (Hasse's Entdeck. 2, 37; comp. Euseb. Proep. Evang. 10, 6; Diod. Sic. 1, 20; Buttmann, Mythol. 1, 164; Kalisch, Commentary, ad loc.).
