Have you ever asked any of these questions?
What can I learn from Jabal?
What can I learn from Jubal?
What can I learn from Tubal-Cain?
Probably not. These names are among the more obscure ones in Biblical history. That being said, when we look at what is said about them and the context in which they are found, there are valuable insights to be gleaned. First, by way of creating context, these men are descendants of Cain and sons of his descendant, Lamech. Lamech was a murderer and the first polygamist in Biblical history. He had two wives: Adah and Zillah; and the aforementioned men were the sons of these two women respectively.
