Genesis 4:19-21

And Lamech took for himself two wives; the name of the one was Adah, and the name of the other, Zillah. Adah gave birth to Jabal; he became the father of those [nomadic herdsmen] who live in tents and have cattle and raise livestock. His brother’s name was Jubal; he became the father of all those [musicians] who play the lyre and flute.
