King James Bible Dictionary

The strikerdown; the wild man.

1. The fifth in descent from Cain. He was the first to violate the primeval ordinance of marriage (Genesis 4:18-24). His address to his two wives, Adah and Zillah (4:23, 24), is the only extant example of antediluvian poetry. It has been called "Lamech's sword-song." He was "rude and ruffianly," fearing neither God nor man. With him the curtain falls on the race of Cain. We know nothing of his descendants.

2. The seventh in descent from Seth, being the only son of Methuselah. Noah was the oldest of his several sons (Genesis 5:25-31; Luke 3:36).

poor; made low

1. Father of Jabal, Jubal, and Tubal-Cain

(powerful), properly Lemech.

1. The fifth lineal descendant from Cain. (Genesis 4:18-24) He is the only one except Enoch, of the posterity of Cain, whose history is related with some detail. His two wives, Adah and Zillah, and his daughter Naamah, are, with Eve, the only antediluvian women whose names are mentioned by Moses. His three sons, Jabal, Jubal and Tubal-cain, are celebrated in Scripture as authors of useful inventions. The remarkable poem which Lamech uttered may perhaps be regarded as Lamech's son of exultation on the invention of the sword by his son Tubal-cain, in the possession of which he foresaw a great advantage to himself and his family over any enemies.
2. The father of Noah. (Genesis 5:29)
