Answer: As Cain appears to be no obscure type of the unbelieving Jews who rose up against and slew Him Who deigned to be born of that people, and have since been left wandering over the face of the earth; so Lamech appears, in this song to his two wives, to represent the Jew in the latter day confessing his blood-guiltiness, yet looking to be avenged most amply at the end. Thus we know from the prophets it will be with Israel, when a land is brought forth in one day, and a nation is born at once. For as soon as Zion travailed, she brought forth her sons. Then shall the people, once so guilty yet kept, and henceforth truly penitent at the feet of Messiah, sing, O Jehovah, Thy mercy is forever.
