Genesis 4:20

And Adah bare Jabal . Either the Traveler or the Producer, from yabhal , to flow; poetically, to go to walk; hiphil, to produce; descriptive, in the one case, of his nomadic life, in the other of his occupation or his wealth. He was the father — av , father; used of the founder of a family or nation ( Genesis 10:21 ), of the author or maker of anything, especially of the Creator'( Job 38:28 ), of the master or teacher of any art or science ( Genesis 4:21 )— of such as dwell in tents, and of such as have cattle. Mikneh , literally, possession, from kanah , to acquire, as in Genesis 4:1 ; hence cattle, as that was the primitive form of wealth (cf. pecus , pecunia ); by which may be meant that Jabal was the first nomad who introduced the custom of living in tents, and pasturing and breeding not sheep merely, but larger quadrupeds as well, for the sake of wealth.
