From Genesis 4:
16And Cain went out from the presence of the Lord, and dwelt in the land of Nod, on the east of Eden.
17And Cain knew his wife; and she conceived, and bare Enoch: and he built a city, and called the name of the city, after the name of his son, Enoch.
18And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech.
19And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah.
20And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle.
21And his brother’s name was Jubal: he was the father of all such as handle the harp and organ.
22And Zillah, she also bare Tubal–cain, an instructor of every artificer in brass and iron: and the sister of Tubal–cain was Naamah.
From Albert Pike’s Esoterika:
Tubalcain was “an instructor of every artificer ii?i brass and iron.” That is all that we are told of him, except that he was the son of Lamech and Zillah; the brother of Naamah. Gen. 4:16?22.
But the Hebrew is not correctly translated. It is Tubal Kin latas kal?kbaras nakbsat ur barzal; which means, “Tubal Kayin, a beater, (hammerer or forger), sharpener or polisher, of every work of brass and iron” He was a smith working on those metals?a blacksmith and coppersmith. Gesenius gives as a meaning, perhaps, scoriarum faber, “Worker in dross or slag” which means nothing at all. What sort of work would that be?
tbl: “Fertile land, habitable land, habitable world, whole orb of the world;’ universus tcrrarum orbt’s. Gesenius. The world, the earth, peculiarly the habitable part of it, its inhabitants, mankind. Lee.
Kain, same as Kanah, brought forth, created.
Kanah, whence ikin,yakin,jacbtn, “erected, made, stand erect:” means “founded, created,” e.g., heaven and earth, men: canine, “creature” Gesenius.
The same verb in Arabic is said to mean “to forge:’ Gesenius. Newman.
Tubal?kayin may have meant “Creator of the World;’meaning the Creative Word The Demiourgos. But I think that the word was selected simply on its account of it being the name of the first artisan, a Fellow of the Craft.
