The fifth in descent from Cain. He was the first to violate the primeval ordinance of marriage ([Gen. 4:18-24](/gen#Gen.4.18)). 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.
