Easton
the son of Lamech and Zillah, "an instructor of every artificer in brass and iron" (Ge 4:22; R.V., "the forger of every cutting instrument of brass and iron").
Hastings
In Ge 4:22 'the father of every forger of copper and iron' (so read, with slight textual correction), i.e. the founder of the guild or profession of metal-workers. The name seems to be made up of Tubal (or the Tibareni, noted for production of bronze articles (Eze 27:13)) and Cain ('smith'), as the ancestor of the Kenites or 'Smiths.'

Morish
Son of Lamech and Zillah. He was an instructor of every artificer in brass and iron, or a forger of every kind of brass and iron tool. Ge 4:22.
It is remarkable, and it is doubtless not without a purpose, that these metals should be mentioned so early. It quite confutes the theory that all mankind have risen from some degraded position, and that they must have passed long periods in using stone implements before they used metals. This may be true of some who fell far below the moral status of Adam and Eve after their fall. Ro 1:24,26 explains much: "God gave them up" to their lusts because they turned their backs on Him.

TUBAL-CAIN, or THUBAL-CAIN, son of Lamech the bigamous, and of Zillah, Ge 9:29. The Scriptures tell us, that he was the father and inventor, or master, of the art of forging and managing iron, and of making all kinds of iron-work. There is great reason to believe that this was the Vulcan of the Heathens.
