JABAL (jā'băl, Heb. yāvāl, meaning uncertain). A son of Lamech, who was the great-grandson of Cain (Gen.4.19-Gen.4.20). He and his brothers, Jubal and Tubal-Cain, are credited with the origin of civilized society (Gen.4.21-Gen.4.22).

JABAL jā’ bəl (יָבָ֑ל). The first son of Lamech and Adah; he was “the father of those who dwell in tents and have cattle” (Gen 4:20).

International Standard Bible Encyclopedia (1915)

In Ge 4:20, a son of Lamech by Adah. He is called `the father of those who dwell in tents and (with) herds.’ So Gunkel, Gen3, 52, who says that the corresponding word in Arabic means "the herdsman who tends the camels." Skinner, Gen, 120, says that both Jabal and Jubal suggest yobhel, which in Phoenician and Hebrew "means primarily `ram,’ then `ram’s horn’ as a musical instrument, and finally `joyous music’ (in the designation of the year of Jubilee)." See also Skinner, Gen, 103, on the supposed connection in meaning with Abel.
