GENESIS 4:19-21 (KJV)

¹⁹And Lamekh took unto him two wives: the name of the one was Adah, and the name of the other Zillah. ²⁰And Adah bare Yabal: he was the father of such as dwell in tents, and of such as have cattle. ²¹And his brother’s name was Yubal: he was the father of all such as handle the harp and organ.
